# *~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*

# This example of input file, intended for CLASS beginners, lists all
# possibilities with detailed comments. You can use a more concise version, in
# which only the arguments in which you are interested would appear. Only lines
# containing an equal sign not preceded by a sharp sign "#" are considered by
# the code, any other line is considered as a comment.
#
# The normal syntax is:      parameter = value(s)
# where white spaces do not matter (they are removed automatically by the
# parser unless they are part of the parameter name).
# However,                   'parameter' = value(s)
# and                        "parameter" = value(s)
# are also accepted by the parser since v2.8.0
#
# Input files must have an extension ".ini".



# -------------------------
# ----> General parameters:
# -------------------------

# 1) List of output spectra requested:
#       - 'tCl' for temperature Cls,
#       - 'pCl' for polarization Cls,
#       - 'lCl' for CMB lensing potential Cls,
#       - 'nCl' (or 'dCl') for density number count Cls,
#       - 'sCl' for galaxy lensing potential Cls,
#       - 'mPk' for total matter power spectrum P(k) infered from gravitational
#         potential,
#       - 'dTk' (or 'mTk') for density transfer functions for each species,
#       - 'vTk' for velocity transfer function for each species
#       - 'sd' for spectral distortions
#    Warning: both lCl and sCl compute the C_ls of the lensing potential,
#    C_l^phi-phi. If you are used to other codes, you may want to deal instead
#    with the deflection Cls or the shear/convergence Cls. The relations
#    between them are trivial:
#        --> deflection d: Cl^dd = l(l+1) C_l^phiphi
#        --> convergence kappa and shear gamma: the share the same harmonic
#            power spectrum: Cl^gamma-gamma = 1/4 * [(l+2)!/(l-2)!] C_l^phi-phi
#    By defaut, the code will try to compute the following cross-correlation
#    Cls (if available): temperature-polarisation, temperature-CMB lensing,
#    polarization-CMB lensing, CMB lensing-density, and density-lensing. Other
#    cross-correlations are not computed because they would slow down the
#    code considerably.
#
#    Can be left blank if you do not want to evolve cosmological perturbations
#    at all. (default: set to blank, no perturbation calculation)
# output = tCl,pCl,lCl,mPk
# output = tCl,pCl,rCl
output = tCl,pCl,rCl
# output = tCl,pCl,lCl
# output = mPk,mTk
# output = Sd

# 1.a) If you included 'tCl' in the list, you can take into account only some
#      of the terms contributing to the temperature spectrum:
#         - intrinsic temperature corrected by Sachs-Wolfe ('tsw' or 'TSW'),
#         - early integrated Sachs-Wolfe ('eisw' or 'EISW'),
#         - late integrated Sachs-Wolfe ('lisw' or 'LISW'),
#         - Doppler ('dop' or 'Dop'),
#         - polarisation contribution ('pol' or 'Pol').
#      Put below the list of terms to be included (defaut: if this field is not
#      passed, all terms will be included)
#temperature_contributions = tsw, eisw, lisw, dop, pol

# 1.a.1) If one of 'eisw' or 'lisw' is turned off, the code will read
#        'early/late isw redshift', the split value of redshift z at which the
#        isw is considered as late or early (if this field is absent or left
#        blank, by default, 'early/late isw redshift' is set to 50)
#early_late_isw_redshift =

# 1.b) If you included 'nCl' (or 'dCl') in the list, you can take into account
#      only some of the terms contributing to the obsevable number count
#      fluctuation spectrum:
#          - matter density ('density'),
#          - redshift-space and Doppler distortions ('rsd'),
#          - lensing ('lensing'),
#          - or gravitational potential terms ('gr').
#      Put below the list of terms to be included (defaut: if this field is not
#      passed, only 'dens' will be included)
#number_count_contributions = density, rsd, lensing, gr

# 1.c) If you included 'dTk' (or 'mTk') in the list, the code will give you by
#      default the transfer function of the scale-invariant Bardeen potentials
#      (for whatever gauge you are using). If you need the transfer function of
#      additional metric fluctuations, specific to the gauge you are using, set
#      the following flag to 'yes' (default: set to 'no')
#extra_metric_transfer_functions = yes


# 2) If you want to consider perturbed recombination, enter a word
#    containing the letter 'y' or 'Y'. CLASS will then compute the
#    perturbation in the ionization fraction x_e and the baryon
#    temperature, as in 0707.2727. The initial conformal time will be
#    small, therefore you should use the default integrator ndf15
#    (i.e. do not set 'evolver' to 0, otherwise the code will be
#    slower).  (default: no, neglect perturbed recombination)
#perturbed_recombination = yes

# 3) List of modes:
#         - 's' for scalars,
#         - 'v' for vectors,
#         - 't' for tensors).
#      More than one letter allowed, can be attached or separated by arbitrary
#      characters; letters can be small or capital. (default: set to 's')
modes = s
#modes = s,t

# 3.a) List of initial conditions for scalars:
#           - 'ad' for adiabatic,
#           - 'bi' for baryon isocurvature,
#           - 'cdi' for CDM isocurvature,
#           - 'nid' for neutrino density isocurvature,
#           - 'niv' for neutrino velocity isocurvature.
#        More than one of these allowed, can be attached or separated by arbitrary
#        characters; letters can be small or capital. (default: set to 'ad')
ic = ad
#ic = ad&bi&nid

# 3.b) Which perturbations should be included in tensor calculations?
#           - write 'exact' to include photons, ultra-relativistic species 'ur'
#             and all non-cold dark matter species 'ncdm';
#           - write 'massless' to approximate 'ncdm' as extra relativistic species
#             (good approximation if ncdm is still relativistic at the time of
#             recombination);
#           - write 'photons' to include only photons
#        (default: set to 'massless')
tensor_method =


# 4) Gauge
# 4.a) Gauge in which calculations are performed:
#         - 'sync' or 'synchronous' or 'Synchronous' for synchronous,
#         - 'new' or 'newtonian' or 'Newtonian' for Newtonian/longitudinal gauge
#      (default: set to synchronous)
gauge = synchronous

# 4.b) Do you want to output the N-body gauge quantities as well?
#      If you included 'dTk' or 'vTk' in the list of outputs, you may transform
#      your transfer functions into the Nbody gauge by setting the following
#      flag to 'yes'. This will also include the transfer function for the
#      metric perturbations H_T' (exact) and gamma (approximate) in the Nbody gauge.
#      See e.g. 1505.04756, and equations (A.2) and (A.5) in 1811.00904
#      for more precise definitions. These calculations are more stable with
#      'gauge=synchronous' (default). To compute H_T' and gamma
#      without converting the output to the Nbody gauge,
#      please use the flag 'extra metric transfer functions' instead.
#      Can be set to anything starting with 'y' or 'n'.
#      (default: set to 'no')
#nbody_gauge_transfer_functions = yes

# 5) Hubble parameter : either 'H0' in km/s/Mpc or 'h' or '100*theta_s', where
#    the latter is the peak scale parameter defined exactly as 100(ds_dec/da_dec)
#    with a decoupling time given by maximum of visibility function (quite different
#    from theta_MC of CosmoMC and slightly different from theta_* of CAMB)
#    (default: 'h' set to 0.67810 such that 100*theta_s = 1.041783 like in Planck 2018)
h = 0.67810
#H0 = 67.810
#100*theta_s = 1.041783


# 6) Primordial Helium fraction 'YHe', e.g. 0.25; if set to 'BBN' or 'bbn',
#    will be inferred from Big Bang Nucleosynthesis (default: set to 'BBN')
YHe = BBN


# 7) 'recombination' algorithm set to 'RECFAST' or 'HyRec'. 'HyRec' points at HyRec 2020. Its compute time is negligible compared to other CLASS modules. 'RECFAST' points at RecFastCLASS, an enhanced version of RecFast 1.5 with better integration shceme and less discontinuities. Recfast is still slightly faster than HyRec but less accurate. HyRec is better for most purposes. RecFast can still be useful for studying some particular modifications of standard recombination. Both schemes use the CLASS ODE integrators. (Default: HyRec')
recombination = HyRec

# 7.a) If recombination algorithm is set to 'RECFAST'
#      the photo-ionization coefficients beta(T) for normal Recfast depend on Tmat
#      This is an approximation (see e.g. arxiv:1605.03928 page 10, arxiv:1503.04827 page 2, right column)
#      With 'recfast_photoion_dependence' the photo-ionization coefficient beta(T) is set to depend on
#          - 'Tmat' uses beta(Tmat) depending on matter temperature
#                   (like in original RECFAST and in CLASS v2.x)
#          - 'Trad' uses beta(Trad) depending on radiation temperature
#                   (while this option is theoretically more motivated, the option 'Tmat' leads to
#                    results which agree better with HyRec and CosmoRec. This is probably due to the
#                    fudge factor for the Peebles coefficient being optimized for a Tmat dependence)
#      (default: set to 'Tmat')
recfast_photoion_dependence =


# 8) Parametrization of reionization: 'reio_parametrization' must be one of
#       - 'reio_none' (no reionization),
#       - 'reio_camb' (like CAMB: one tanh() step for hydrogen reionization one
#         for second helium reionization),
#       - 'reio_bins_tanh' (binned history x_e(z) with tanh()  interpolation
#         between input values),
#       - 'reio_half_tanh' (like 'reio_camb' excepted that we match the
#         function xe(z) from recombination with only half a tanh(z-z_reio)),
#       - 'reio_many_tanh' (arbitrary number of tanh-like steps with specified
#         ending values, a scheme usually more useful than 'reio_bins_tanh'),
#       - 'reio_inter' (linear interpolation between discrete values of xe(z)).
#    (default: set to 'reio_camb')
reio_parametrization = reio_camb

# 8.a) If 'reio_parametrization' set to 'reio_camb' or 'reio_half_tanh':
#      enter one of 'z_reio' or 'tau_reio' (default: 'z_reio' set to 7.6711 to
#      get tau_reio of 0.054308), plus 'reionization_exponent',
#      'reionization_width', 'helium_fullreio_redshift',
#      'helium_fullreio_width'. (default: set to 1.5, 0.5, 3.5, 0.5)
z_reio = 7.6711
#tau_reio = 0.05430842
reionization_exponent = 1.5
reionization_width = 0.5
helium_fullreio_redshift = 3.5
helium_fullreio_width = 0.5

# 8.b) If 'reio_parametrization' set to 'reio_bins_tanh':
#      enter number of bins and list of z_i and xe_i defining the free electron
#      density at the center of each bin. Also enter a dimensionless paramater
#      regulating the sharpness of the tanh() steps, independently of the bin
#      width; recommended sharpness is 0.3, smaller values will make steps too
#      sharp, larger values will make the step very progressive but with
#      discontinuity of x_e(z) derivative around z_i values. (default: set to
#      0, blank, blank, 0.3)
binned_reio_num = 3
binned_reio_z = 8,12,16
binned_reio_xe = 0.8,0.2,0.1
binned_reio_step_sharpness = 0.3

# 8.c) If 'reio_parametrization' set to 'reio_many_tanh':
#      enter number of jumps, list of jump redhsifts z_i (central value of each
#      tanh()), list of free electron density x_i after each jump, and common
#      width of all jumps. If you want to end up with all hydrogen reionized
#      but neglecting helium reionization, the first value of x_i in the list
#      should be 1. For each x_i you can also pass the flags -1 or -2. They
#      mean:
#         - -1: after hydrogen + first helium recombination (so the code will
#               substitute a value bigger than one based on Y_He);
#         - -2: after hydrogen + second helium recombination (the code will
#               substitute an even bigger value based on Y_He).
#      You can get results close to reio_camb by setting these parameters to
#      the value showed below (and adapting the second many_tanh_z to the usual
#      z_reio). (default: not set)
many_tanh_num = 2
many_tanh_z = 3.5,11.3
many_tanh_xe = -2,-1
many_tanh_width = 0.5

# 8.d) If 'reio_parametrization' set to 'reio_inter': enter the number of
#      points, the list of redshifts z_i, and the list of free electron
#      fraction values x_i. The code will do linear interpolation between them.
#      The first z_i should always be 0. Like above, for each x_i, you can also
#      pass the flags -1 or -2. They mean: for -1, after the hydrogen and the
#      first helium recombination (so the code will substitute a value bigger
#      than one based on Y_He); for -2, after the hydrogen and the second
#      helium recombination (the code will substitute an even bigger value
#      based on Y_He). The last value of x_i should always be zero, the code
#      will substitute it with the value that one would get in absence of
#      reionization, as computed by the recombination code. (default: not set)
reio_inter_num = 8
reio_inter_z =   0,  3,  4,   8,   9,  10,  11, 12
reio_inter_xe = -2, -2, -1,  -1, 0.9, 0.5, 0.1,  0


# 9) State whether you want the code to compute the simplest analytic
#    approximation to the photon damping scale (it will be added to the
#    thermodynamics output, and its value at recombination will be stored and
#    displayed in the standard output) (default: 'compute damping scale' set to

# previous default value of 3.046) (note: instead of 'N_ur' you can
# pass equivalently 'N_eff', although this syntax is deprecated) (one
# more remark: if you have respectively 1,2,3 massive neutrinos, if
# you stick to the default value T_ncdm equal to 0.71611, designed to
# give m/omega of 93.14 eV, and if you want to use N_ur to get N_eff

#      passed, CLASS will renormalise the psd in order to fulfill both

# -----------------------------------------
# ----> Exotic energy injection parameters:
# -----------------------------------------

# 1) DM Annihilation

# 1.a) In order to model energy injection from DM annihilation, specify a
#      parameter 'annihilation_efficiency' corresponding to
#      <sigma*v> / m_cdm expressed here in units of m^3/s/J. Alternatively,
#      you can specify the annihilation cross section in cm^3/s and the DM
#      mass in GeV. The code will then evaluate 'annihilation_efficiency'.
#     (default: all set to zero)
DM_annihilation_efficiency = 0.
#DM_annihilation_cross_section = 0.
#DM_annihilation_mass = 0.
#DM_annihilation_fraction = 0.

# 1.a.1) You can model simple variations of the above quantity as a function of
#        redhsift. If 'annihilation_variation' is non-zero, the function F(z)
#        defined as (<sigma*v> / m_cdm)(z) (see 1.a) will be a parabola in log-log scale
#        between 'annihilation_zmin' and 'annihilation_zmax', with a curvature
#        given by 'annihilation_variation' (must be negative), and with a maximum
#        in 'annihilation_zmax'; it will be constant outside this range. To
#        take DM halos into account, specify the parameters 'annihilation_f_halo',
#        the amplitude of the halo contribution, and 'annihilation_z_halo',
#        the characteristic redshift of halos (default: no variation,
#        'annihilation_variation' and 'annihilation_f_halo' set to zero).
DM_annihilation_variation = 0.
DM_annihilation_z = 1000
DM_annihilation_zmax = 2500
DM_annihilation_zmin = 30
DM_annihilation_f_halo= 0
DM_annihilation_z_halo= 8


# 2) DM electromagnetic decay

# 2.a) Specify the dimensionless parameter 'decay_fraction' which is
#      equal to the fraction of cdm with electromagnetic decay
#      products (decaying into dark radiation is handled by
#      Omega_dcdm).  Note: Until class 2.7, this parameter was called
#      'decay'. Its name and its meaning have slightly changed to
#      avoid confusion when working with model in which the lifetime
#      of the dcdm can be small (this is allowed providing that the
#      'decay_fraction' parameter is small as well).  (default: set to
#      0)
DM_decay_fraction = 0.

# 2.b) Specify the decay width of the particle 'decay_Gamma' in 1/s.
#      (default: set to 0)
DM_decay_Gamma = 0.


# 3) PBH evaporation. In this case, check that in 5), 'f_eff_type' and
# 'f_eff' have their default values 'on_the_spot' and 1, because CLASS
# will automatically take into account the time-dependent efficiency
# of energy injection from evaporating BH, taking the spectrum of
# evaporated particles into account.

# 3.a) Specify a dimensionless parameter 'PBH_evaporation_fraction' which is equal
#      to the fraction of evaporating PBH. (default set to 0)
PBH_evaporation_fraction = 0.

# 3.b) Specify the mass of the evaporating PBH in g. (default set to 0)
PBH_evaporation_mass = 0.


# 4) PBH matter accretion

# 4.a) Specify a dimensionless parameter 'PBH_accreting_fraction' which is equal
#      to the fraction of accreting PBH. (default set to 0)
PBH_accretion_fraction = 0.

# 4.b) Specify the mass of the accreting PBH in Msun. (default set to 0)
PBH_accretion_mass = 0.

# 4.c) Specify the 'PBH_accretion_recipe' between 'spherical_accretion'
# (computed according to Ali-Haimoud and Kamionkowski 1612.05644), or
# 'disk_accretion' (computed according to Poulin et al. 1707.04206).
# (default set to 'disk_accretion')
PBH_accretion_recipe = disk_accretion

# 4.c.1) If you choose 'spherical_accretion', you might want to specify the
#        relative velocity between PBH and baryons in km/s.
#        If negative, the linear result is chosen by the code.
#        (default set to -1., standard value is the linear result extrapolated to PBH.)
PBH_accretion_relative_velocities = -1.

# 4.c.2) If you choose 'disk_accretion', you might want to specify the
#        factor 'PBH_accretion_ADAF_delta' which, determines the heating
#        of the electrons in the disk, influencing the emissivity.
#        Can be set to 0.5 (aggressive scenario), 0.1 or 1.e-3 (conservative).
#        (default set to 1.e-3)
#        Furthermore you can also specify the the eigenvalue of the accretion
#        rate. It rescales the perfect Bondi case. (see e.g. Ali-Haimoud
#        & Kamionkowski 2016) (default set to 0.1, standard value in the ADAF
#        scenario.)
PBH_accretion_ADAF_delta = 1.e-3
PBH_accretion_eigenvalue = 0.1

# 5) Define the so-called injection efficiency f_eff, i.e. the factor
#    determining how much of the heating is deposited at all,
#    regardless of the form. There are two options to define this
#    function: 'on_the_spot' or 'from_file' (default: set to 'on_the_spot').
#
#    - with 'on_the_spot', the injected energy is transformed into deposited energy
#      at the same redshift with efficiency f_eff. In this case the
#      user can pass explicitely the value of f_eff. (default: f_eff=1)
#
#    - for 'from_file' the code reads a precomputed function in an external file
#      with a path set by the user (default set to "/external/heating/example_f_eff_file.dat")
f_eff_type = on_the_spot
#f_eff =
#f_eff_file = external/heating/example_f_eff_file.dat

# 6) Define the so-called deposition function chi, i.e the function which determines
#    the amount of energy effectively deposited into the different forms (heating,
#    ionization, Lyman alpha and low energy). There are several options
#        - by setting 'chi_type' to 'CK_2004', the approximation by Chen & Kamionkowski 2004 is employed.
#        - by setting 'chi_type' to 'PF_2005', the approximation by Padmanabhan & Finkbeiner 2005 is employed.
#        - by setting 'chi_type' to 'Galli_2013_file', the approximation by Galli et al. 2013 is employed.
#        - by setting 'chi_type' to 'Galli_2013_analytic', the approximation by Poulin is employed.
#          interpolating Galli et al. 2013 anyltically. Use this for consistency tests with
#          older versions of CLASS (2.x).
#        - by setting 'chi_type' to 'heat', the whole injected energy is going
#          to be deposited into heat.
#        - by setting 'chi_type' to 'from_x_file' or 'from_z_file', the user can
#          define own deposition functions with respect to the free electron
#          fraction x_e or to redshift, respectively.
#    (default set to 'CK_2004')
chi_type = CK_2004

# 6.a) If the option 'from_file' has been chosen, define the name of the file.
#      Two files 'example_chix_file.dat' and 'example_chiz_file.dat' are given
#      as example in external/heating. Note that 'example_chix_file.dat' has
#      been computed according to the approximations of Galli et al. 2013.
#      (default set to "/external/heating/example_f_eff_file.dat")
#chi_z_file = external/heating/example_chiz_file.dat;
#chi_x_file = external/heating/example_chix_file.dat;

# ----> Non-linear parameters:
# -------------------------------

# 1) If you want an estimate of the non-linear P(k) and Cls:
#    Enter 'halofit' or 'Halofit' or 'HALOFIT' for Halofit
#    Enter 'hmcode' or 'Hmcode' or 'HMcode' or 'HMCODE' for HMcode;
#    otherwise leave blank (default: blank, linear P(k) and Cls)
non_linear =

# 1.a) if you chose Halofit, and you have Omega0_fld != 0. (i.e. you
# set Omega_lambda=0.) & wa_fld != 0.,  then you might want to use the
# pk equal method of 0810.0190 and 1601.07230 by setting this flag to
# 'yes' (default: set to 'no')
pk_eq =

# 1.b)  if you chose HMcode:
#    In HMcode you can specify a baryonic feedback model (otherwise only DM is used).
#    Each model depends on two parameters: the minimum concentration "c_min" from the
#    Bullock et al. 2001 mass-concentration relation and the halo bloating parameter "eta_0"
#    introduced in Mead et al. 2015. In Mead et al. 2015 the parameters c_min and eta_0 are fitted
#    to the Cosmic Emulator dark matter only simulation (Heitman et al. 2014) and the
#    hydrodynamical OWLS simulations (Schaye et al. 2010, van Daalen et al. 2011).
#    You can choose between the 5 models of Mead et al. 2015, Table 4:
#      Model           (eta_0, c_min) Explanation
#    - 'emu_dmonly'    (0.603, 3.13)  fits the only dark matter Cosmic Emulator simulation (default)
#    - 'owls_dmonly'   (0.64, 3.43)   fits the OWLS simulation of dark matter only
#    - 'owls_ref'      (0.68, 3.91)   fits the OWLS simulation that includes gas cooling, heating,
#                                     star formation and evolution, chemical enrichment and supernovae feedback
#    - 'owls_agn'      (0.76, 2.32)   fits the OWLS simulation that includes AGN feedback
#    - 'owls_dblim'    (0.70, 3.01)   fits the OWLS simulation that has extra supernova energy in wind velocity
#    Set 'feedback model' to one of these names,
#    or leave blank and pass manually the value of either 'eta_0' or 'c_min'
#    (the other one will then be fixed according to equation (30) in Mead et al. 2015),
#    or pass manually the two values of 'eta_0' and 'c_min'
#    (default: 'feedback model' set to 'nl_emu_dmonly')

# ----> Primordial parameters:
# ----------------------------

# 1) Primordial spectrum type
#       - 'analytic_Pk' for an analytic smooth function with amplitude, tilt,

#         a new type;
#       - 'inflation_V' for a numerical computation of the inflationary
#         primordial spectrum, through a full integration of the perturbation
#         equations, given a parametrization of the potential V(phi) in the
#         observable window, like in astro-ph/0703625;
#       - 'inflation_H' for the same, but given a parametrization of the
#         potential H(phi) in the observable window, like in
#         astro-ph/0710.1630;
#       - 'inflation_V_end' for the same, but given a parametrization of the
#         potential V(phi) in the whole region between the observable part and
#         the end of inflation;
#       - 'two scales' allows to specify two amplitudes instead of one
#         amplitude and one tilt, like in the isocurvature mode analysis of the
#         Planck inflation paper (works also for adiabatic mode only; see
#         details below, item 2.c);
#       - 'external_Pk' allows for the primordial spectrum to be computed
#         externally by some piece of code, or to be read from a table, see
#         2.d).
#    (default: set to 'analytic_Pk')
Pk_ini_type = analytic_Pk

# 1.a) Pivot scale in Mpc-1 (default: set to 0.05)
k_pivot = 0.05

# 1.b) For type 'analytic_Pk':

#ln10^{10}A_s = 3.04478383
# sigma8 = 0.824398

# 1.b.1.1) Adiabatic perturbations:
#          tilt at the same scale 'n_s', and tilt running 'alpha_s'
#          (default: set 'n_s' to 0.9660499, 'alpha_s' to 0)

#          entropy perturbations), enter the entropy-to-curvature ratio f_xx,
#          tilt n_xx and running alpha_xx, all defined at the pivot scale; e.g.
#          f_cdi of 0.5 means S_cdi/R equal to one half and (S_cdi/R)^2 to 0.25
#          (default: set each 'f_xx' to 1, 'n_xx' to 1, 'alpha_xx' to 0)

f_cdi=1.
f_nid=1.
n_nid=2.
alpha_nid= 0.01
# etc.

# 1.b.1.3) Cross-correlation between different adiabatic/entropy mode:
#          for each pair (xx, yy) where 'xx' and 'yy' are one of 'ad', 'bi',
#          'cdi', 'nid', 'niv', enter the correlation c_xx_yy (parameter between
#          -1 and 1, standing for cosDelta, the cosine of the cross-correlation
#          angle), the tilt n_xx_yy of the function cosDelta(k), and its running
#          alpha_xx_yy, all defined at the pivot scale. So, for a pair of fully
#          correlated (resp. anti-correlated) modes, one should set (c_xx_yy,
#          n_xx_yy, alpha_xx_yy) to (1,0,0) (resp. (-1,0,0) (default: set each
#          'c_xx_yy' to 0, 'n_xx_yy' to 0, 'alpha_xx_yy' to 0)

# etc.

# 1.b.2) For tensor perturbations (if any):
#        tensor-to-scalar power spectrum ratio, tilt,
#        running at the pivot scale; if 'n_t' and/or 'alpha_t' is set to 'scc'

# 1.c) For type 'inflation_V'

#          lensing potential)
#    Reducing 'l_max_lss' with respect to l_max_scalars reduces the execution

#      widths separated by comas, 1 or N bias separated by a comma, and 1 or N
#      magnification bias separated by a comma. The width stands for one
#      standard deviation of the gaussian (in z space), or for the half-width of
#      the top-hat. Finally, non_diagonal sets the number of cross-correlation
#      spectra that you want to calculate: 0 means only auto-correlation, 1
#      means only adjacent bins, and number of bins minus one means all
#      correlations (default: set to 'gaussian',1,0.1,1.,0.,0)

#      NOTE: For good performances, the code uses the Limber approximation for

#            l_switch_limber_for_nc_local_over_z and

# 2.c) It is possible to consider source number counts evolution. Type the name

#P_k_max_1/Mpc = 0.7

# 3.a.1) If you want to use a different value for k_max in the primordial and

#        'primordial_P_k_max_1/Mpc' in units of 1/Mpc
#        to define the maximum value of k for primordial power spectrum. By doing
#        so, 'P_k_max_h/Mpc' will only apply to perturbations. If unspecified,
#        'primordial_P_k_max_h/Mpc' is assumed to be the same as 'P_k_max_h/Mpc'.

# 2) Should the lensing potential [phi+psi](k,tau) and the lensing spectrum Cl_phiphi be rescaled?
#    You can rescale [phi+psi](k,tau) at all times by an overall amplitude and tilt: lcmb_rescale*(k/lcmb_pivot)**lcmb_tilt
#    Or, more simply, you can pass the usual parameter 'A_l', and the potential will be rescaled by sqrt(A_L)
#    (matches standard definition in Calabrese et al. 0803.2309)

#        analysis? The value can vary between 0 and 6. (default set to 2)

#        In external/distortions, the file detectors_list.dat contains a list
#        of currently "known" detectors, i.e. detectors for which the PCA decomposition
#        has already been computed. If no detector name is specified, but the detector specifics
#        1.a.3.x) are, the name will be created automatically. If no name and no specifics are
#        given, PIXIE values are going to be assumed.

#        already precumputed.
#
#        It would be very helpful if, once computed the vectors for a new detector, the user would

# 5.a) Specify the type of approximation you want to use for the SZ effect
#        - by setting 'sd_reio_type' to 'Nozawa_2005', the approximation by Nozawa et al. 2005 is employed.
#        - by setting 'sd_reio_type' to 'Chluba_2012', the approximation by Chluba et al. 2012 is employed.
