- 094-1200 : 2013+370 : adjustment of R2DE clk power level 2.0 dBm to 2.5 dBm just before scan, seems to have distrupted R2DBE so it reports huge clock offset; NOEMA correlator also suffered a hang-up; scan probably not good; re-ran
runstart_backend.py and M6_CC after this scan - 094-1211 : 2013+370 : started ok : vdiftimeUDP ok, recording ok, power levels slightly high i.e. a bit of clipping, adjusting analog levels down after the scan : relatively good
- 094-1218 : 2013+370 : ok, powers levels not adjusted yet, local fringes most stable 12:11:40--12:18:10, good
