Ho: iread power levels are a bit low 28000 and 38000 of 48000 | changing attentuation did nothing to help (OHG109)
mot an issue: got a different frequency range for O'Higgins (uses Mark 4 rack), slightly smaller range, different power and temperatures. Not paying attention to read in this experiment. Needs more tests.
Tsys temperatures below 200 now seem okay, probably degradation of the system. Measured wrong due to absolute calibration error but maybe 10-20% due to the degradation.
Ho: problems with cryo temp (OHG109 and AUA031)
Just summer maybe. Also receiver pressure a bit dodgy, at 4 microns. Build of gases, got over 5 microns last night but was pumped down. Summer season so cryo problems likely to be more of an issue. Keep an eye out.
Ke: Ran fivept several times, the offsets are looking a bit dodgy (AUA031)
Problem after bad storms in Katherine. Bryn could get below 0.04 offset even after several attempts. Jamie to work on this.
Similarly, fringe testing is quite rubbish these days.
Yg: alarms going off for illegal state error and unable to read systemclock1. antenna=open antenna=operate fixed the issue (R1816)
