6	! Purpose
7	! -------
8	! Calculates the H2-H2 CIA opacity, using a lookup table from
9	! HITRAN (2011 or later)
10	!
11	! Authors
12	! -------
13	! R. Wordsworth (2011)
14	!
15	! + J.Vatant d'Ollone (2019)
16	! - Enable updated HITRAN file (Karman2019,Fletcher2018)
17	! (2018 one should be default for giant planets)
