Detailed Description

CIA data for a single pair of molecules.

A variable of this class can hold the complete information from one HITRAN CIA file. A HITRAN CIA data file can hold several datasets (data for different temperatures but fixed frequency range). But all datasets are for the same pair of molecules.

Parameters

[in]	frequency	Scalar frequency
[in]	temperature	Scalar temparature
[in]	dataset	Index of dataset to use
[in]	robust	Set to 1 to suppress runtime errors (and return NAN values instead).
[in]	verbosity	Standard verbosity object.

		const Index &	robust,
		const Verbosity &	verbosity
	)		const

Vector version of extract.

Check whether there is a suitable dataset in the CIARecord and do the interpolation.

Parameters

[out]	result	CIA value for given frequency grid and temperature.
[in]	f_grid	Frequency grid.
[in]	temperature	Scalar temparature.
[in]	dataset	Index of dataset to use.
[in]	robust	Set to 1 to suppress runtime errors (and return NAN values instead).

Member Data Documentation

◆ mdata

ArrayOfGriddedField2 CIARecord::mdata

private

The data itself, directly from the HITRAN file.

Dimensions: Array dimension: Dataset. One file (one molecule pair) can have different datasets, typically for different temperature or frequency ranges. Gridded field dimension 1: Frequency [Hz]. Gridded field dimension 2: Temperature [K]. Data: Binary absorption cross-sections in m^5 molec^(-2)

◆ mspecies

Index CIARecord::mspecies[2]

private

The pair of molecules associated with these CIA data.

Molecules are specified by their ARTS internal mspecies index! (This has to be determined upon reading from a file. Should it ever be written out, it has to be mapped to a string again.)

We use a plain C array here, since the length of this is always 2.
