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.
