Nov 16th, Tuesday
15:00-00:25, 10th IRAM 30m School - Observing slots of Working Groups III (4.5h lost: sub-reflector mounted without servo-amplifiers; then, a failure appeared in the local oscillator box of EMIR-E0: solved by SN) & II (observing OK with NIKA2).
Nov 17th, Wednesday
00:35-03:00, Angel: Restarting acquisition, cryo run 68. Opacity below 0.2. Stable. Imbfits creation restarted twice: OK. Pointing/focus on W3OH. Three repetitions on PSZ2G141 (project 199-16).
A timelapse of Manuel Castillo Fraile from this morning:
03:00-09:00, Nicolas Ponthieu on shift. Starting with Angel and Sergio, telescope focused, pointing on Uranus, beam map (20211117s28), calib_1scan (s29), skydip (s30), then one rep of 199-16/PSZ2G141 to complete, then 192-16/cosmos until 9am with focus/pointing around 5h50 and 8h10. The night went smoothly.
09:00-15:00, Angel, Gianluca (invited for further observing training): Opacity around 0.2 about the first third of the shift. 192-16/cosmos continued for ~1h. Then, we got 1.5 reps. on AK4-224 cluster (084-21) with tau225 = 0.20 to 0.25. Some instabilities appeared after that, with opacity increasing from 0.3 to 0.4. Acquisition restarted at 48 Hz at 12h (UT; starting from scan 20211117s124) and 2 reps. were obtained on cluster A1835 of ARSENAL sample (086-21). A broadening of about 1-2 arcsec in the beam size with the best focus correction was observed at the last part of the shift. NIKA2 observations stopped after a calib_1scan on Mars (20211117s141; broadened beam) skydip (s143).
15:00-00:00, 10th IRAM 30m School - Observing slots of Working Groups I and V (everything OK). At the end of the 2nd slot, Working Group V (orange) obtained calib_1scan on NGC7027 (20211117s232), CRL2688 (s233), MWC349 (235) after pointing/focusing on the first source. Then, a beam map on 2251+158 (s244).
