    Notes

    • PV joined late due to bad weather. The first scans were bad due to a setup problem. First good scan is 091-1415 No0265. Looks like the 3rd-last scan for PV, i.e. PV lost for most of this track.
    • YS had technical problems in the beginning of c221a which were fixed after 091-0800 No0179. Missing quarter waves plates were inserted later. First good scan is 091-1415 No0267, the 3rd-last scan for YS.
    • KU no fringes for the most part except No0155-No0181
    • Mopra is linear polarized (PolConvert!) and had a different recording setup than scheduled, 2 x 2048 MHz at 85244.0 MHz USB.
    • Mopra 20 scans of data lost at MPIfR due to VDIF conversion running while BeeGFS migration was ongoing, unfortunately no back on transfer server
    • Atca had a non-standard setup, most likely 4 x 64 MHz USB at 86012.0 MHz and 86076.0 MHz
    • AT had fringes AT-MP in realtime monitoring at 12:00:02 UT albeit low-SNR(?) and likely polswapped,
