abs_cia_dataReadFromCIA

Workspace.abs_cia_dataReadFromCIA(self, abs_cia_data: pyarts3.arts.ArrayOfCIARecord | None = None, abs_species: pyarts3.arts.ArrayOfSpeciesTag | None = None, catalogpath: pyarts3.arts.String | None = None) → None

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

The units in the HITRAN file are:

• Frequency: \(\textrm{cm}^{-1}\)

• Binary absorption cross-section: \(\textrm{cm}^{5} \, \textrm{molec}^{-2}\)

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