NOTE [1]: The CONBIA option is station dependent, therefore the station ID
          is required.
                                                                                
NOTE [2]: Only one CONBIA card is needed to constrain a number of adjacent
          periods from MBIAS.  If some periods from the MBIAS stream are 
          excluded from constrained adjustments, use as many CONBIA cards 
          as the number of sets of continuous adjacent periods.
