<p class="MsoNormal"><span style="font-size:11.0pt">I cc’d the PWG list because Caterina, Aris, at al., may be able to give you some guidance regarding the latest polarisation calibration for the beamformed data, and if it’s advised to apply it to this data.
The instrumental polarisation doesn’t look too bad from the Faraday spectrum to me, but they may have more comments about this.
