Fixing limb darkening coefficients

[gapp-c]

I see that there are two limb darkening parameters (u1, u2) in the fit_par file and the option fix_ld in the pcf. Thus, to fix the LD parameters, one could either fix their values to given numbers in the fit_par file or use model results from exotic-LD for them using the pcf. When I state in both files that I want to fix them, which values have priority?

Yeah, fixing the limb-darkening (LD) values in PACMAN based on an exotic-ld run hasn't been tested thoroughly yet. If you want to use a literature value for the LD parameter(s) I would just set it in the fit_par.

I agree that "fix_ld" is a confusing name for a parameter. It should be rather called "use_ld_file" because it should eventually set if the user wants to use the precalculated LD values in the ld_file or not.
