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.

IN	abs_species	(ArrayOfArrayOfSpeciesTag)	Tag groups for gas absorption.
IN	select_abs_species	(ArrayOfSpeciesTag)	A select species tag group from abs_species If set to empty, this selection is void.
IN	jacobian_quantities	(ArrayOfRetrievalQuantity)	The retrieval quantities in the Jacobian matrix.
IN	f_grid	(Vector)	The frequency grid for monochromatic pencil beam calculations.
IN	rtp_pressure	(Numeric)	Pressure at a radiative transfer point.
IN	rtp_temperature	(Numeric)	Temperature at a radiative transfer point.
IN	rtp_vmr	(Vector)	Absorption species abundances for radiative transfer calculations.
IN	xsec_fit_data	(ArrayOfXsecRecord)	Fitting model coefficients for cross section species.
GIN	force_p	(Numeric, Default: -1)	Positive value forces constant pressure [Pa].
GIN	force_t	(Numeric, Default: -1)	Positive value forces constant temperature [K].
