BPASSPRM
Type: Adverb (Array(11))
Use:  Bandpass calibration control parameter array.
Tasks:
  BPASS.....Computes spectral bandpass correction table
  CPASS.....Computes polynomial spectral bandpass correction table
            BPASSPRM use - see task helps for details
            (1) if > 0 use only the autocorrelation data.
            (2) print level.
            (3) If > 0 do not divide data by source model
            (4) If > 0 store phases only in the BP table.
            (5) Divide by 'channel 0' control:
                  0 -> divide by channel 0 amp and phase each time
                 -1 -> divide by channel 0 phase only each time
                 -2 -> divide by channel 0 after scan average
                  1 -> do no division by channel 0
            (6) amp closure error limit - print channels averaging
                over this if (2) > 0
            (7) phase closure error limit print channels averaging
                over this if (2) > 0
            (8) > 0 => scalar average amplitudes
            (9) > 0 => interpolate over flagged channels if poss.
            (10) 0 => no deliberate normalization after solutions
                      found.
                 1 => normalize amplitudes using all channels
                 2 => normalize amplitudes using ICHANSEL channels
                 3 => normalize amplitudes and zero average phase
                      using ICHANSEL channels
                 4 => normalize amplitudes and zero average phase
                      using all channels
                 5 => normalize amplitudes and zero average phase
                      using ICHANSEL channels - normalizes power
                      (square of BP function) not function itself
                 6 => normalize amplitudes and zero average phase
                      using all channels - normalizes power (square of
                      BP function) not function itself
                 7 => normalize amplitudes and zero average phase using
                      ICHANSEL channels and medians
                 8 => normalize amplitudes and zero average phase using
                      all channels and medians
                 9 => normalize amplitudes only using ICHANSEL channels
                      and medians
                10 => normalize amplitudes only using all channels and
                      medians
             (11) > 0 solution weights are independent of channel
                  <=0, > -1.5 weights scaled by amplitude**2
                  < -1.5 weights scaled by 1 / amplitude**2
