     [1]: In multiple satellite runs (like GPS runs), a separate ORBFIL         
          option card is needed for each satellite.  The same start and         
          stop times on each card should be used.                               
                                                                                
                                                                                
     [2]: If master satellite and its slaves are output as a set (column        
          8=1), individual members of the set may still be output in            
          separate files by including separate ORBFIL card(s) for the           
          desired satellite(s).
