PROFILER v2.0

*Slight update in the code as of 8 March 2018

Change-log from version 1.0

1. GUI features

• display additional panels with isophote parameters (higher order Fourier harmonics, Bn, n>4);
• change units for the x- and y- axis (e.g. kpc, arcsec ...) directly input by user, in LaTeX syntax;
• add "filter" as subscript to mu (surface brightness);
• save settings (PSF, zero-point mag ... everything above the model components) and load these from saved file;
• save parameters (same as above but WITH the model components and their last updated parameters);
• new frame for entering model components, with scrollbar;
• clear components from frame;
• update component guess-values with best-fit parameters;

2. Magnitudes

• analytical magnitudes only provided in log file if fit is done along equivalent axis;
• numerically integrated magnitudes provided in addition to (where applicable) analytical results:
  --> useful for components without analytical magnitude expressions (e.g. inclined disc, etc)
  --> accurate to within 0.05 mag in most cases, except if function changes very sharply over very narrow radial range, or becomes very shallow and goes on to infinity (e.g. Sersic functions with n>7 - note however that these WILL have analytical magnitudes)
