Set the radiation source type
source type
where type is either solar or thermal.
Solar radiation is per default output in W/(m2 nm) for spectral and
correlated_k LOWTRAN calculations. For all other correlated_k options
the output is integrated over the wavelength band.
Thermal radiation is per default output in W/(m2 cm-1), if the bandwidth
is equal to 1 cm-1 (default for correlated_k LOWTRAN calculations).
Otherwise the output is the integrated flux over the
wavenumber interval specified by thermal_bandwith, thermal_bands_file,
or by the correlated_k option (kato, kato2, kato2.96,
fu, or avhrr_kratz).
