Homogeneous Path Transmittance
RFM Examples		03AUG26

Description

*FLG section

HOM flag: homogeneous path calculation

TRA flag: output the transmittance spectrum.

*GAS section

H2O and CO2 are to be included

*ATM section

For homogeneous paths the simplest way to specify the path conditions is directly entering p, T and VMR values in the *ATM section

*LEN section

By default path lengths are in km, but can be changed to m (or cm, mm) using the UNITS= keyword
