New Ticket: Polarization Calibration
Hi,
I am reducing 1667 MHz OH spectral line data from project AC319 (JUN-92, polarizations RR, LL, RL, LR). Observations include 2 calibrators-1328+307(3C286) as flux and polarizatio calibrator and 1827-360 as a phase calibrator. I am using AIPS31DEC2010 version.
I am trying to do polarization calibration but having problems with 'pcal'.
AIPS cookbook says that pcal should be run on the phase calibrator. When I run pcal, it deletes my AN table and the task aborts. I don't understand what is going wrong here. I have used following inputs for pcal:
