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: 114 (ar1), 4 (ar2), 113 (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.
