DESCRIPTION = "This file consists of processed radiometer data records.  Each 
  logical record will correspond to a single radiometer measurement, and will 
  contain the results of operating the radiometer while pointing the          
  spacecraft's anntenna at 'cold space'.  The blackbody source temperature    
  (radiation temperature) expected from such a measurement is that of the     
  cosmic background: 2.7K.  Cold-sky calibration measurements are perfomed    
  three times during the mission: at the beginning, the end, and once at      
  'mid-mission'.  The data are processed to obtain the blackbody source       
  temperature.  Each F-BIDR contains in this file all of the collected        
  cold-sky calibration data.  For some F-BIDR products, this file may be      
  empty.  For more information, refer to SDPS-101, Magellan Software          
  Interface Specification, Full-Resolution Basic Image Data Record, K. Leung, 
  JPL, Revision E, August 31, 1992."
