GALFITools: A Python library to enhance GALFIT usage in galaxy image modeling - GALFITools v1.18.0

GALFITools: A library for GALFIT

GALFITools constitutes a collection of specialized routines to facilitate the utilization of GALFIT. The toolkit encompasses a spectrum of routines, spanning from mask creation, Point Spread Function (PSF) creation, Multi-gaussian expansion, sky computation, initial parameter estimation, to the analysis of GALFIT's output

In this release:

• New function (getBT) to compute the bulge to total luminosity ratio
• New function (getMeRad) to compute the surface brightess and mean surface brightness at a any radio
• skyRing and skyDs9 functions computes the surface brightness of the sky
• better documentation
• bugs fixed
