HELP SECTION

POLANGLE
Type: Array(30)
Use:  To give a list of up to 30 polarization angles in degrees.

Default: 0 => none - task will fill in for known sources, e.g. 3C286
                     is 33 degrees at all frequencies.

Tasks:
  RLDIF.....Determines the difference in phase between the right and
            left polarization calibrations - requires CALIB, PCAL, and
            BPASS to be run first.  Then it determines the remaining
            phase difference between right and left from the RL and LR
            phases.  POLANGLE is used to determine the exact phase
            correction as 2*POLANGLE(i) - RLphase(i) to be added to L,
            where i is the i'th included source in source number
            order.
