RFM Flags

DBL Flag: Write Spectra with Double Precision

15SEP05

Enabled

Output spectra written with full (ie double) precision

Disabled

Output spectra truncated to single precision

Restrictions

Incompatible with TAB flag

Notes

1. Internally, the radiative transfer integration is always performed with Double Precision but uses Single Precision absorption coefficients (since most line parameters are only known with this accuracy). Double Precision output is only really necessary when considering transmittances close to 1.0 (in which case writing absorption, = 1-transmittance, spectra would be better), or when comparing different RFM runs with minor perturbations.
