Notes. For each antenna, listed are the fractional amplitude, m, and phase, χ, of the instrumental polarization (polarization leakage) in the right (RCP) and left (LCP) circular polarization channel and in the first (IF1, top row) and second (IF2, bottom row) intermediate frequency channel. The D-term phases have been corrected for the phase offsets obtained from the EVPA calibration described in Sect. 3.2.4.
