Workspace Method propmat_clearskyAddXsecFit


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.
