   The LMB table contains values derived from spectra that look at the 
   limb of Mars.  It contains one record for each limb set - sequential 
   observations that view the limb at different altitudes.  See the limb 
   parameters quality word for information on the validity of calculated 
   variables.  The aerosol information may include data from surface 
   observations taken at other times of the same geographic location.

   The uncertainty array provides error information for surface radiance 
   spectrum values taken near the same time."
