astrobase v0.3.11

New stuff

• checkplot.checkplot_pickle_to_png: can now export to StringIO or BytesIO instance in addition to a PNG filename.
• checkplot/lcproc: added a maxnumneighbors kwarg to control the max number of neighbors the function retrieves around the target object. Added by Joshua Wallace (@joshuawallace).
• cpserver UI: added object-neighbor color and mag diffs per neighbor to the overview tab if available.
• cpserver UI: zoom effects on mouse-over for phased LC tiles to make reviewing easier.
• lcproc.make_lclist/filter_lclist: can now make overlayed FITS finder charts if a FITS file for the object catalog is provided. The lc-collection-work Jupyter notebook has more details.
• plotbase: added a fits_finder_chart function to make an annotated finder chart from a given FITS file with WCS information.

Changes

• cpserver UI: finder chart reticle appearance changed slightly to obscure stars near the target less.
• cpserver UI: moved the 'Save to PNG' button to the overview tab so it's more obvious.
• checkplot:checkplot_pickle: can now fall back to GAIA proper motions if 'pmra' and 'pmdecl' are not provided in the input objectinfo dict kwarg.
• cpserver: now gzips the response (slightly speed up if the checkplotserver is running somewhere else other than localhost).
• cpserver: PNG export for a checkplot is now done in memory (theoretically, this enables PNG export in readonly mode, but that's disabled for now).

Fixes

• checkplot.checkplot_pickle_to_png: fix py2 StringIO isinstance() issues.
• cpserver: fix broken handling of missing nbr mag and color diffs.
• cpserver UI: fix the CSV/JSON export to correctly include all previous reviewed objects instead of just the ones from the current session.
• cpserver: readonly mode now disables all input correctly.
• cpserver UI: fix checkplot list traverse breaking at ends of list.
• periodbase.kbls.bls_snr: fixed transit duration calculation, pointed out in Github PR #45.
• lcproc: fix readerfunc apply if sequences are returned.

astrobase v0.3.9

New stuff

• checkplot: can now provide epochs for folding phased light curves as input, overriding the default light curve time-of-minimum finding strategy
• starfeatures and checkplot: can now use arbitrary mags and colors in input objectinfo dicts, can add custom bandpasses as well
• checkplotserver UI: added highlight for each GAIA neighbor in the DSS finder chart as cursor mouses over its row in the GAIA neighbor list table to help with visualizing close neighbors
• tests: added tests for new epoch and mag/color handling
• added a CITE.md

Changes

• checkplot: no longer warns if a pickle was written in Python 2 and latin1 encoding was needed to read it in Python 3
• checkplot: a Savitsky-Golay fit is now tried before giving up on finding time-of-minimum of a light curve if the initial spline fit failed
• checkplotserver: UI fixes to not squish phased LC tiles into too small an area; now they overflow off the page with scroll-bars, but should remain legible
• lcmath.sigclip_magseries can now use either median/MAD or mean/stdev as the central and spread values in determining where to clip (added by @joshuawallace in #40)

Fixes

• checkplotserver: handle more nan-JSON breakage
• starfeatures: handle missing information correctly
• fixed link at the top of hatlc.py to the astrobase-notebooks repository (added by @adrn in #37)

Changes

• setup.py: use pip>=6 requirements format; allows conditional py2 dependency on the backported future package, instead of the hack we had before
• lcproc.filter_lclist: get the whole matching row from the external catalog for xmatches instead of just the objectid
• lcfit.legendre_fit_magseries: add legendre fit coeffs to output dict
• removed imageutils.py, moved to another package in development
• periodbase: periodepsilon is now a fraction diff from previous peak instead of an absolute diff, should work better for finding peaks in the periodograms for all period ranges now

• kbls: fixing nphasebins and messaging about autofreq
• starfeatures.neighbor_gaia_features: handle missing K mag
