Create .prf file containing internal
profile of absorbers and levels actually used
Internal Profile not written out.
The internal profile contains profiles of temperature, pressure
and VMRs etc on the set of levels used for the internal forward
model. This is a combination of the user-supplied files in the
in the *ATM section interpolated to the first
height or pressure
grid (removing any VMR profiles for species not selected in the
*GAS section), plus any additional
levels that may be introduced by the
The profile is output in the same format as
.atm input files.
For 1D calculations a single file is written, but for 2D calculations
(GRA Flag) separate files are
written for every specified horizontal angle.
