RFM Flags

WNG Flag: Use Far-wing Cutoff for Lines

28NOV17

This flag will be discontinued from RFM v5 onwards
Enabled
Only include lines within 200 Voigt halfwidths of grid points within fine-mesh calculation

Disabled
Include all lines within adjacent widemesh intervals (3 x 1 cm-1 intervals)

Restrictions
Incompatible with GRD Flag.

Notes
  1. The WNG flag only affects the fine-mesh calculation. The main purpose is to avoid spending time computing absorption coefficients for Doppler-broadened lines which are well beyond the line half-width.
  2. The number of half-widths for exclusion (200) is set by the parameter NWDCUT in rfmcon.inc.
