09:00-15:00; Lara: 13:35: cryostat intervened by Dave John and Alessandro Monfardini. P5 stabilised and 2mm pre-amplifier restarted. DAQ restarted at 14:00: bad KIDs: 54 (ar1), 9 (ar2), 65 (ar3). |
09:00-15:00; Lara: three runs done for NGC4254 until 10:00. Clear sky, tau almost stable around 0.25, peak to peak fluctuations < +/- 6 Jy/b, rms < 2 Jy/b. After this moved to MWC349 for pointing, focus, calib_1scan + another calib_1scan on NGC7027. Then I did a skydip. At 11 some checkings with NIKA2 and EMIR where done for possible wifi contaminations. 13:35: cryostat intervened by Dave John and Alessandro Monfardini. P5 stabilised and 2mm pre-amplifier restarted.

15:15-21:00; Miguel, Angel: Technical time (T06-22) scheduled up to Wed. 04:00 (LT). Checking interference spikes in EMIR data after asking CETURSA IT team for switching off suspicious Wi-Fi systems of the lift booths close to the telescope. In principle, no interference spikes were detected after ad-hoc technical observations. Tau_225GHz is about 0.25 and stable. Switching to NIKA2 DAQ started at 16:50; bad KIDS: 61 (ar1), 9 (ar2), 71 (ar3). Noise traces (on-sky) of ar2, ar1 and ar3 are given below. A quick pointing session (11 sources at 70 < Az. < 381 deg and 27 < El. < 69 deg) for refining corrections was carried out from 20:20 to 21:50.
21:00-03:00; Manuel, Angel: Opacity keeps stable (tau_225GHz < 0.25). Pointing session was finished. Resulting statistics: <pAz.> = -0.46 +/- 1.38 arcsec, <pEl.> = 6.25 +/- 0.64 arcsec. Continued with a calib_1scan on Uranus (20220110s245), a skydip (s246), and a calib_1scan on ALFORI (s249). Only the parameter P7 of the pointing model was corrected accordingly and checked before scan s257. Fairly stable after a brief opacity increase. Pointing and focus on Uranus. Beam map on Uranus (s258). Starting science observations: project 105-22; one rep. (35 min) on B213-C6; project 122-16 (GASTON), 2 reps. on B213E_N; project 192-16 (N2CLS) started: 1 rep. on COSMOS field.

03:00-09:00; Jean-François: clear sky, Tau_225 stable around 0.25, peak-to-peak fluctuations < 5Jy/b and rms=2-3Jy/b at 2mm all night. Project 192-16 on COSMOS for 3 hours (hit attenuation limit); 199-16 PSZ2G212 for 1.5 hours (i.e. 3rep) (hit attenuation limit) ; focus ; 169-22 GJ526North 1 hour ; focus ; start 160-16 NGC4254 and pass over to Lara.
09:00-15:00; Lara: three runs done for NGC4254 until 10:00. Clear sky, tau almost stable around 0.25, peak to peak fluctuations < +/- 6 Jy/b, rms < 2 Jy/b. After this moved to MWC349 for pointing, focus, calib_1scan + another calib_1scan on NGC7027. Then I did a skydip.
