callcorrk.F90 @ 1672

Last change on this file since 1672 was 1648, checked in by jvatant, 9 years ago

Modifications to custom radiative transfer to Titan
+ Enables an altitude dependant gfrac for CIA computations

-> many radical changes in su_gases and co ..
-> read vertical CH4 profile with call_profilgases
-> Now you need a 'profile.def' that I will add in the deftank

+ Added interpolate CIA routines for CH4
+ Added temporary mean aerosol profile opacity routine (disr_haze)
