Identifier   band_2_det

 Purpose      Convert a SWS band to the absolute detector(s)

 Synopsis     det = band_2_det(band,stat=stat)

 Arguments    Name  I/O Type:      Description:
              --------------------------------------------------------
              band   I  intarr     Selected detectorband(s) (0,1..6) (0=all 
                                   bands)
              stat I /O int        error status, 0 if ok, 1 if fatal 

 Description  This routine converts the SWS bandnumber to an integer array
              of detector numbers

              Defined  number of det per band: [12,12,12,12,2,2] 
              Band range: 0,1-6,   Channel  range: 1-52

 Returns      The absolute detector number(s) (1..52)

 Comment      --

 Example      det= band_2_det(1)
              this yields an array det = [1,2,3,4,5,6,7,8,9,10,11,12]
