C241A Correlation Report
General information
- Session info: http://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/
- Station feedback: Gl late due to storm (https://docs.google.com/spreadsheets...gid=1941489491), bad weather at Pv in the beginning and at Ef, Ys lost scans 0376, 0377, Mh was offline 2024-04-19 1228 to 1400 UTC, c241a was observed from 109-22:00 to 110-06:50 UT, 110-10:00 to 110-10:37 UT. Nn did not observe due to storm in the beginning, then due to a cabling error, we were on the "regular" 3mm band R&S SMA 100A synthesizer that was referenced to the maser (it should have sufficient quality for VLBI, however). We switched to the VLBI specific R&S SMA 100B just before starting c241b, and the following observations of c241b and c241c were done with it, Aa good, no KT
Status
| what | date |
|---|---|
| started e-transfer for PV(2/2), Ys, On, Mh, sent email to KVN/Mp (awaiting start), Ef done | 22.04.2024 |
| Fringes between Pv, On, Ys, Ef, Mh, sync error for Mh and probably Ys (missing frames) but only in the first few scans? | 24.04.2024 |
| KVN data transfer started (complete), At & Mp still missing, but contacted via email to check | 26.04.2024 |
| GLT, AA on the way, JCMT not yet | 12.06.2024 |
| AA arrived, to be scanned in, JCMT is halfway through the data transfer, JCMT done | 05.07.2024 |
| GLT arrived, filelist done, looking for fringe done | 21.08.2024 |
| Correlation commenced, test run through, comments below | 22.08.2024 |

Notes
From test run: KVN_PC has a significant delay, due to the double peak problem, KVN has a big delay rate offset w.r.t. to LA. fixed.
