TAB Flag
RFM Flags: Create Look-Up Tables of Absorption Coefficient		10APR24

Enabled

Create .tab files containing look-up tables of absorption coefficient. Tabulation is of ln(k), where k is the absorption cross-section in [m²/kmol] (1 kmol is approx 6E26 molecules)
Interpret *TAN as *DIM section specificying p,T,q tabulation axes.
Disabled: No tabulated absoption coefficients written
Restrictions: Incompatible with ABS, AVG, BBT, BFX, CLC, DBL, FLX, FOV, GEO, GRA, ILS, JAC, LEV, LOS, NAD, OBS, OPT, PTH, RAD, SFC, TRA and ZEN Flags.
Notes

The .tab files created with this option can also be used as RFM inputs, when they are known as Look-Up Tables.

RFM Use of Look-Up Tables

If GHZ Flag is enabled, the absorption coefficients are specified on a GHz spectral axis

To create tables for different isotopes, you can either

perform separate RFM calculations with different single isotopes specified in the *GAS section (output files will all have the same default filename and no internal information on the isotope
perform a single RFM run, specifying different profiles for each isotope in the files in the *ATM section. In this case the output filenames and internal information are also modified.
The second method is recommended.

See RFM Outputs for default filename(s), which can be modified using the *OUT Section
