◆ find_broad_spec_locations()

void find_broad_spec_locations	(	ArrayOfIndex &	broad_spec_locations,
		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const Index	this_species
	)

Find the location of all broadening species in abs_species.

Set to -1 if not found. The length of array broad_spec_locations is the number of allowed broadening species (in ARTSCAT-4 N2, O2, H2O, CO2, H2, H2). The value means:

-1 = not in abs_species

-2 = in abs_species, but should be ignored because it is identical to Self

N = species is number N in abs_species

The catalogue contains also broadening parameters for "Self", but we ignore this here, since we know the position of species "Self" anyway.

Return values

broad_spec_locations See above.

Parameters

abs_species	List of absorption species
this_species	Index of the current species in abs_species

◆ xsec_species()

void xsec_species	(	MatrixView	xsec_attenuation,

		ConstMatrixView	all_vmrs,

		const Index	ind_ls,
		const Index	ind_lsn,
		const Numeric	cutoff,
		const SpeciesAuxData &	isotopologue_ratios,
		const Verbosity &	verbosity
	)

Calculate line absorption cross sections for one tag group.

All lines in the line list must belong to the same species. This must be ensured by abs_lines_per_speciesCreateFromLines, so it is only verified with assert. Also, the input vectors abs_p, and abs_t must all have the same dimension.

This is mainly a copy of abs_species which is removed now, with the difference that the vmrs are removed from the absorption coefficient calculation. (the vmr is still used for the self broadening)

Continua are not handled by this function, you have to call xsec_continuum_tag for those.

Return values

xsec	Cross section of one tag group. This is now the true absorption cross section in units of m^2.

Parameters

f_grid	Frequency grid.
abs_p	Pressure grid.
abs_t	Temperatures associated with abs_p.
all_vmrs	Gas volume mixing ratios [nspecies, np].
abs_species	Species tags for all species.
this_species	Index of the current species in abs_species.
abs_lines	The spectroscopic line list.
ind_ls	Index to lineshape function.
ind_lsn	Index to lineshape norm.
cutoff	Lineshape cutoff.
isotopologue_ratios	Isotopologue ratios.
