v3.1

OMEGA-Py v3.1 – Updates

From the release of version 3.0, OMEGA-Py has been officially validated by the OMEGA team and is distributed as an official OMEGA software alternative to the IDL version. https://www.ias.u-psud.fr/omega/software.html

A complete online documentation has been written and is available at https://astcherbinine.github.io/omegapy/

Version 3.1 corresponds to the release associated with the publication in the Journal of Open Source Software.

omega_data

• Add recursive search in subfolders for OMEGA files binaries when calling omega_data.OMEGAdata.__init__()
• Add BD_omega function to compute band depth criteria on OMEGA observations

omega_plots

• Fix use_V_geom in interactive display

v3.0 - Official

OMEGA-Py v3.0 - Official – Major updates

From the release of version 3.0, OMEGA-Py has been officially validated by the OMEGA team and is distributed as an official OMEGA software alternative to the IDL version.

A complete online documentation has been written and is available at https://astcherbinine.github.io/omegapy/

Updates to the omega_data.OMEGAdata class

• Improve binaries processing to have a perfect match with the IDL version of the code, force the use of float32 instead of float64
• Add focal plane and spectrometer temperatures for all channels
• Add incidence and emergence angles w.r.t. the local normal (in addition to the ellipsoid)
• Add omega.ref_C, surface reflectance map to be compared with cos(inci_n) to check the geometry spatial calibration
• Add geometry information for the V-channel (which is slightly different to the one of the V+L channels)
• Add distance to Sun in km (in addition to a.u. value)

omega_plots

• Add option to use the V-channel geometry in all the display functions that use projection (use_V_geom=True)

omega_data

• Add option to filter only the data cubes acquired with nadir geometry in find_cube (nadir_only=True)

v2.4

OMEGA-Py v2.4 - Updates

omega_data

• Add omega_mask function to generate masks used in the omega_plots functions.

omega_plots

• Add new projection method for composite maps: proj_method=2 accounts for the entire footprint of each pixel to create high-resolution maps. But it takes much more time to process.

v2.3

OMEGA-Py v2.3 - Updates

Fixes several issues related to the use of the module with Windows.

omega_data

• Fix compatibility issues with Windows for the importation and correction of OMEGAdata objects.
• Disable the use of multiprocessing for thermal correction with Windows.
• Fix definition of custom paths for binary and python files with set_omega_bin_path() and set_omega_py_path().

omega_plots

• Add the mask argument in show_omega().
• Fix gaps between pixels in composite maps.

v2.2

OMEGA-Py v2.2 - Updates

Update script functions from SOFT09 to SOFT10: extent the L-channel correction up to orbit 13131 (see the SOFT10 README for more details).

omega_data

• Add the get_header_qub and get_header_nav methods to the OMEGAdata class
• Change average datetime to median datetime (OMEGAdata and find_cube) to fix issue with partially corrupted geometry informations

omega_plots

• Add the **kwargs argument *v2 plots functions. Pass additional parameters of the plt.colormesh function for the plot.

v2.1

OMEGA-Py v2.1 - Updates

omega_data

• Add the display (disp) option to OMEGAdata
• Improve the version managing of saved OMEGAdata objects

omega_plots

• Add the negative_values argument for composite maps

useful_functions

• Add support of NaNs for the where_closer() and where_closer_array() functions

v2.0 - Full Python !

OMEGA-Py v2.0 - Major updates

• omega_data :

  • Full Python 3 implementation (no longer requires the use of IDL backend routines)
  • Add my attribute in the OMEGAdata class
  • Allow user to apply or not corrections on channel V or L during the reading of the binaries

• omega_plots :

  • Add usage of masks in all the dislay functions
  • Add possibility to choose the longitude range between [0, 360] and [-180, 180] with negatives_longitudes
  • Possibility to extract and replot picked spectra from interactive plots
  • Function show_ibd_v2() renamed to show_data_v2()

v1.4.2

OMEGA-Py v1.4.2 - Updates

• Add multiprocessing option for the thermal correction (npool parameter)
• Improve the axis limits and zoom for show_omega_list_v2()
• Add Save & Restore functions for composite maps

v1.4

OMEGA-Py v1.4 - Major updates

• Add the following attributes to the OMEGAdata class :
  • sensor_temp_c
  • saturation_c
  • saturation_vis
  • summation
  • bits_per_data
  • data_quality
  • target
• Add getters for OMEGAdata lists :
  • omegapy.omega_data.get_ls(omega_list)
  • omegapy.omega_data.get_names(omega_list)

v1.3

OMEGA-Py v1.3 - Major updates

• Add loct attribute to the OMEGAdata class : the array of local time for each pixel as a float between 0 and 24.
• Improve the observation display : possibility to add a grid and display a high-level map (e.g. IBD) for interactive use.
• Some variables and functions dedicated to internal use were switch to private (e.g. omega_py_path -> _omega_py_path).
