broad.c file with new evaluation of quadratic Stark effect for certain spectral lines (till now, only Mg II h,k and triplets) in RH code . To use it, just replace the broad.c file in your main directory of RH code.
This is a small change to let your RH code use Mg II Stark widths calculated by semi-classical perturbation theory. Besides, you can add some other lines like Si IV with a little effort.
Tested on RH1.5D, should also work on 1D verson (rhf1d).
Have fun!
