		const ArrayOfLineRecord &	abs_lines,
		const Index	ind_ls,
		const Index	ind_lsn,
		const Numeric	cutoff,
		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.
abs_h2o_orig	Total volume mixing ratio of water vapor.
vmr	Volume mixing ratio of the calculated species.
abs_lines	The spectroscopic line list.
ind_ls	Index to lineshape function.
ind_lsn	Index to lineshape norm.
cutoff	Lineshape cutoff.
