Workspace Variable abs_cia_data

HITRAN Collision Induced Absorption (CIA) Data.

This variable holds HITRAN CIA data (binary absorption
cross-sections). The data itself is described in: Richard, C. et al.
(2012), New section of the HITRAN database: Collision-induced
absorption (CIA), J. Quant. Spectrosc. Radiat. Transfer, 113,
1276-1285, doi:10.1016/j.jqsrt.2011.11.004.
 
The binary absorption cross-sections have to be multiplied with the
densities of both molecules to get absorption coefficients.

Dimensions:

The outer array dimension in the ArrayOfArrayOfCIARecord is the same
as that of abs_species. There will be CIA data only for those
species that contain a CIA tag, for all other species it will be
empty. The inner array dimension corresponds to the number of CIA tags
for this species (there could be for example both N2-N2 and N2-H2) in
the same species.

FIXME: Somewhere there should be a description of the CIA tag system.

Each individual CIARecord holds the complete information from one
HITRAN CIA file. For the given pair of molecules A HITRAN CIA data
file can hold several datasets (data for different temperatures but
fixed frequency range).

Units: 
Frequencies: Hz
Binary absorption cross-sections: m^5*molecule^-2
