03:17 UT Ant 12 is back! It will no doubt have terrible delays. Meanwhile, I am redoing my earlier calibration on 3C273 with parallel and crossed feeds, but now adding parallel and crossed feeds for the equatorial dishes. A total of four scans are being taken, in this order:
- one with the 27-m feed tracking parallactic angle (gives parallel-feed data for azel dishes 1-8, 12),
- one with the 27-m feed tracking parallactic angle + 90 degrees (gives crossed-feed data for azel dishes 1-8, 12),
- one with the 27-m feed rotated by to 90-degrees (gives crossed-feed data for equatorial dishes 9-11, 13),
- one with the 27-m feed unrotated (gives parallel-feed data for equatorial dishes 9-11, 13)
