! Notes on sources relevant to polarisation calibration

! 3C84 - a bright UNPOLARISED source which can be used to
! solve for the instrumental polarisation (D-terms) and the
! RCP/LCP delay difference. The four scans cover a wide range
! in parallactic angle - essential for accurate calibration.

! J0521+16 (3C138) - polarisation position angle calibrator.
! This source is monitored regularly at the VLA so that
! its true position angle of the polarisation is known
! => http://www.aoc.nrao.edu/~smyers/calibration/
! Three scans are used so as to produce an adequate map.
