S30: How to specify the directory containing the exotic-LD data

[gapp-c]

I use s30 to fit white light curves using the attached fit_par.txt and pcf files. With this setup, I expect PACMAN to calculate the quadratic limb darkening coefficients u1 and u2 and use these in the transit model without changing them in the fit. However, I get the following error message:

FileNotFoundError: Model not found for stellar grid=kurucz at path=/home/zieba/Downloads/exotic-ld_data/kurucz/MH-0.1/teff5250/logg4.5/kurucz_spectra.dat.

I don't see a way to change the directory containing the exotic-LD data from the path given in the error message to my own in the pcf, so how do I tell PACMAN where I keep my exotic-LD data?
