| Handover Issues: | Handover Issues: | ||
| - | - Ho: Vacuum pressure leak for receiver cooling system (AUA029) | + | - Ho: iread power levels are a bit low 28000 and 38000 of 48000 | changing attentuation did nothing to help (OHG109) |
| - | * Fixed! Caused by the weather warming. | + | - 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. |
| - | - Ke: Mick changed disk in middle of recording, was the mystery disk that was originally being recorded to every identified? (R4811) | + | - Tsys temperatures below 200 now seem okay, probably degradation of the system. Measured wrong due to calibration but maybe 10-20% the degradation. |
| - | * This was sorted, thanks to Warren. | + | - Ho: problems with cryo temp (OHG109 and AUA031) |
| - | * Make sure to check module allocation sheet. | + | - 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. |
| - | - Yg: Pointing offsets/tracking errors, Note from Arwin in handover notes: "During setup, noticed yg had large offsets in the antenna checks, had to the the pointing checks again and the offsets were better the second time around. This has happened a few times, should this be raised at the meeting?" | + | - Ke: Ran fivept several times, the offsets are looking a bit dodgy (AUA031) |
| - | * The pointing should be OK, Jamie is going to have a squiz. | + | - Yg: alarms going off for illegal state error and unable to read systemclock1. antenna=open antenna=operate fixed the issue (R1816) |
