PPAPP
Type:  Task
Use:   Takes the right minus left polarization phase difference found by
       RLDIF  (or the X - Y phase difference of XYDIF) and applies it to
       a bandpass table of a second data set.
Adverbs:
             *** Data set to be corrected ****
  INNAME.....UV file name (name).       Standard defaults.
  INCLASS....UV file name (class).      Standard defaults.
  INSEQ......UV file name (seq. #).     0 => highest.
  INDISK.....Disk unit #.               0 => any.
             *** Data set with PP table ****
  IN2NAME....UV file name (name).       Standard defaults.
  IN2CLASS...UV file name (class).      Standard defaults.
  IN2SEQ.....UV file name (seq. #).     0 => highest.
  IN2DISK....Disk unit #.               0 => any.
  FREQID.....Frequency identifier to select.  0 -> 1
  SUBARRAY...Subarray number  0 -> 1
  INVERS.....Version of the PP extension file to use.  0 -> high
  BPVER......Version of the BP table to be corrected.  0 -> high
  PDVER......Version of the PD and CP tables to be corrected.  0 -> high
