Changelog
=========

TODO:
 - create an error map associated with the line ratio maps created.

v0.3.1, June 2016, F.P.A. Vogt
 - tied a step to fit_kinematic_pa to derive the P.A. from the velocity maps.
 - added new logo to website.
 - added module to compute the [SII] line ratio - no density for now, just the ratio.
 - fixed a "feature" in aplpy not showing the outer-nan's-only regions in the plots. Now,
   each plot shows the full extent of the MUSE cube, irrespective of how few spaxels are
   actually not NaN's. I use ax._ax1.set_xlim() and ax._ax1.set_ylim() to do so.
 - added ability to add a scale bar to all the plots. 
 - added module to create RGB images from 3 line fluxes.
 - added module to plot line ratio maps.
 - added a gallery to the website.

v0.3.0, May 2016, F.P.A. Vogt:
 - renamed brian to brutus - to avoid conflict with existing brian module on pypi.
 - added computation of LogQ and Tot[O]+12 via pyqz.
 - bug fixes.
 - downloaded additional stellar templates from the MILES library.
 - created a "mixed continuum" cube, used in the interactive fit inspection (and elsewhere).
 - created pyqz plots
 - beefed-up the acknowledgment section of the doc to include the reddening laws, the
   MILES spectral library info, the reference to fit_kinematic_pa.

v0.2.0, May 2016, F.P.A. Vogt:
 - added the ability to rescale the y-axis of the fit residual plots in the interactive 
   fit inspection window
 - updated brian_red, so that the Fischera & Dopita (2005) attenuation law for a turbulent 
   dust screen can now be derived for any Rv and Rva values (use polynomials from the
   article, unlike Appendix A of Vogt+ (2013)). Thanks to R. Sutherland for sharing his
   reddening code that helped me make sense of these polynomials !
 - implemented a processing step to correct for the extragalactic reddening/attenuation
 - added step to correct for galactic extinction, using the NED value for Av and Ab

------------------------------------------------------------------------------------------ 

v0.1.1, April 2016, F.P.A. Vogt:
 - replaced '0.1' with '__version__' when saving fits headers
 - separated the continuum fitting from the construction of the continuum data cube, for
   clarity and consistency with the emission lines
 - added local copy of mpfit as brian_mpfit.py for portability
 - refined plot legends and colorbar ticks
 - started catching numpy warnings in known locations, triggered by all-nan's spaxels
 - implemented a dictionary of created filenames (in brian_metadata), to better keep track 
   of what is created, with much less hard-coded filenames
 - added home-made "alligator" colorbar for that special look (and also to show nan's and
   spaxels that land at the edges or outside a colorbar range for a given plot)
 - connected brian to ppxf
 - defined structure of the docstring, to be used through brian, in brian_cof.lowess_fit
 - added interactive plot to inspect the results of the fit - and the ability to save a
   pretty plot from it
 - bugfixes
  
v0.1.0, April 2016, F.P.A. Vogt:
 - created overall code structure inspired by pywifes
 - implemented continuum fitting using LOWESS approach
 - implemented modular emission line fitting via mpfit
 - added safety measures to catch KeyboardInterrupt during multiprocessing tasks
 - created preliminary documentation structure 
 - initial upload to Github
 - added license info
 - added semi-automatic detection of structures, and ability to interact to add/remove
   apertures of varying radii
 - added creation of "aperture spectra cube" based on a given aperture list
