absorption_cia_dataReadFromCIA

Workspace.absorption_cia_dataReadFromCIA(self, absorption_cia_data: pyarts.arts.ArrayOfCIARecord | None = None, absorption_species: pyarts.arts.ArrayOfArrayOfSpeciesTag | None = None, catalogpath: pyarts.arts.String | None = None) → None

Read data from a CIA data file for all CIA molecules defined in absorption_species.

The units in the HITRAN file are:

• Frequency: cm^(-1)

• Binary absorption cross-section: cm^5 molec^(-2)

Upon reading we convert this to the ARTS internal SI units of Hz and m^5 molec^(-2).
