  from MSWORD save options.

Channel 3B presents filter response values of 0 for some points evenly
   spaced of 102.5wn.... like for Noaa-M
   Bad values are replaced by nearest value (agreement with Jerry)
   This concerns wavenumbers:  2479.00   2581.50  2684.00  2786.50 2889.00

Channel 4 extra lobe around 1080cm-1 is ignored
