petitRADTRANS.opacities.cia.interpolate_cia(collision_dict, combined_mass_fractions, pressures, temperatures, frequencies, mean_molar_masses)#

Interpolate CIA cross-sections onto the Radtrans (wavelength, temperature) grid and convert it into opacities.

Args:

combined_mass_fractions: combined mass fractions of the colliding species: e.g., for H2-He and an atmosphere with H2 and He MMR of respectively 0.74 and 0.24, combined_mas_fractions = 0.74 * 0.24 combined_mas_fractions is divided by the combined weight (e.g. for H2 and He, 2 * 4 AMU^2), so there is no units issue.

Returns:

A (wavelength, temperature) array containing the CIA opacities.
