| Ky | yes, 3mm No0030 50s SNR~250 Kt-Ky | |||
| Ku | yes, 3mm No0159 20s SNR~200 Ku-Ky | most of track no Ku fringes, only during No0155-No0181 | ||
| VLBA | yes, intra VLBA and to Nn Ef | |||
| VLBA_OV | yes | unexpected fringes despite observing log noting rx warm and several maintenance outages while working on the cryo | ||
| VLBA_NL | no | unexpected, no fringes yet no issues noted in observing log; in some sense the opposite of the case of OV | ||
| VLBA_PT | no | expected, observing log indicates Pt had major hardware failures | ||

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,
