Workspace Method propmat_clearskyAddXsecFit
Description
Calculate absorption cross sections per tag group for HITRAN xsec species. This broadens the cross section data from xsec_fit_data and interpolates it onto the current f_grid. Model data needs to be read in with ReadXsecData before calling this method.
