1	subroutine sugas_corrk
2
3	!==================================================================
4	!
5	! Purpose
6	! -------
7	! Set up gaseous absorption parameters used by the radiation code.
8	! This subroutine is a replacement for the old 'setrad', which contained
9	! both absorption and scattering data.
10	!
11	! Authors
12	! -------
13	! Adapted and generalised from the NASA Ames code by Robin Wordsworth (2009)
14	! Added double gray case by Jeremy Leconte (2012)
15	! New HITRAN continuum data section by RW (2012)
