PCFIT
Type:  Task
Use:   To fit pulse-cal amplitudes to generate a bandpass table.

Adverbs:
  INNAME.....Input UV file name (name).      Standard defaults.
  INCLASS....Input UV file name (class).     Standard defaults.
  INSEQ......Input UV file name (seq. #).    0 => highest.
  INDISK.....Disk drive # of input UV file.  0 => any.
  INVERS.....Specifies the version of the PC table to be read as
             input.   0 -> highest.
  FREQID.....Specifies which frequency ID to include.  0 => all
  SUBARRAY...The subarray number to include.  0 => all
  CALSOUR....List of sources for which bandpass response functions are
             to be determined.  All ' ' = all sources; a "-" before a
             source name means all except ANY source named.
  BPARM......The task computes the scan average of the PC table
             amplitudes plus the residual (phase-corrected only) reals
             and imaginaries.  Which of these are used is controlled
             by
             (1) > 0 -> use vector aveage for amplitude, else use
                        scalar average
             (2) > 0 -> use vector average of residuals for phase,
                        else BP phase set to 0.
             (3) > 0 -> take the PC amplitudes as powers rather than
                        voltages (so the BP amplitude is the sqrt of
                        the PC amplitude).  Else take the PC amp as a
                        voltage just like the BP values.
