Version log

v2.2 (20220220)

• plots.plotool
  • Added tick label formatter ‘mylog’ (opitimized for <1 case)
• Added tests/use_cases/

v2.1 (20211202)

• plots.plotool
  • Merged figure to __init__ (using squeeze kw to get self.axes)
  • 0-indexed subpos
  • Supported transformation between coordinate systems with self.trans kw
  • Supported multi-legends by adding reset_handles, append_handles, and get_handles
  • Defined default tick settings in set_ax
  • Clarified **kwargs usage in each function
  • Other kw changes
• plots.pplot
  • Adapted to higher level class changes
  • Defined default uni-plot settings
• Updated tests
• Not compatible with scripts using former version plots.plotool class

v2.0.4 (20211117)

• [VITAL] Fixed kernel selection imaging.iconvolve (should be FWHM instead of Gaussian 1-sigma…)
• imaging.improve
  • Allowed external wgrid input for smooth
• Fixed bugs in plots
  • Set default subpos=(0,0) (keep current axis)

v2.0.3 (20211008)

• Updated output name conventions
  • ‘type’ outputs (e.g. ds): header, data, unc, wave, hyperdata, etc.
  • ‘class’ outputs (e.g. improve): hdr, im, unc, wvl, etc.
  • ‘class’ function ouputs: header(), image(), unc, wave()
• Added rand_pointing to all functions with dist
• Revisited all 3D/2D conditional statements with self.Ndim
• imaging.improve
  • Added original NaN mask for rand_pointing (in order not to invent data at NaN pixels)
  • Changed resampling from ‘by axis’ to ‘by grouped pixels’ for groupixel (NaN mean)
• imaging.iswarp
  • Renamed reproject_mc to combine_mc (which works also for coadding)
• imaging.cupid: minor changes in outputs

v2.0.2 (20211001)

• calib.intercalib
  • Added super pixel support
• imaging.iswarp
  • Added reproject_mc
• Added arrays.pix2sup, arrays.sup2pix, imaging.igroupixel and imaging.ismooth
• Merged imaging.respect to imaging.improve
  • Removed concat (alternative of imaging.concatenate)
  • Renamed old smooth to artifact
  • Added smooth (new) and groupixel
• Renamed imaging.sextract to imaging.cupid
  • Modified inputs variables
  • Added super pixel (non-square rebinning) support
  • Moved rand_pointing to imaging.improve and supported convert pos err to flux unc
  • [VITAL] Reported wrong ispec in spec_build in former version
• Updated tests

v2.0.1 (20210916)

• Imported error ellipse support from a marvelous Python library of F. Galliano
  • arrays: arrayize, ramp
  • plots: plotrange, Btau, Ctau, ellipse and SUE
  • plots.plotool: eplot
• plots.plotool
  • Fixed the bug when any of nrows or ncols equals to 1, self.axes is 1D so self.ax cannot be attributed
  • Added xisln and yisln kw for plot
  • Added close
• plots.pplot
  • Fixed the bug when legend anchor kw appears tight layout is auto deactivated
• Added tests/test_plots.py
• Renamed arrays.allist to arrays.listize

v2.0 (20210914)

• Rename package from laputan to rapyuta due to the French pun…thus it turns to the Ghibli origin!
• plots.plotool
  • Removed set_font and fixed font size and tick problems
  • Added set_legend which supports lengend boxes outside the axes
  • Renamed set_border as set_fig and added suptitle
  • set_ax
    • Added font size kw
    • Renamed xlab as xlabel (idem. for ylab, thus coherent to matplotlib)
    • Changed nonposx default value from ‘sym’ to ‘clip’
  • Note that all kw in set_fig and set_ax can also be executed individually with self.ax.set_kw
