~19:00-22:00; Angel: we took advantage of technical time (T06-21) gentle yielded by Manuel Castillo for NIKA2 general checks and calibrations. Acquisition restarted at ~19:10. Tau(225 GHz) about 0.25, and quite a stable atmosphere with baseline variations between 1 and 3 Jy/beam (2 mm) during this special shift. After checking the right imbfits file creation, we pointed and focused on Uranus. We got FWHMs 17.2"x17.8" (2 mm); 11.0"x11.6" (1 mm); the antenna seems to be a bit unrelaxed according to the maps. Meanwhile, we checked pointing corrections at ~150 < Az. < 300 deg and ~20 < El. 65 deg. Mean corrections obtained are 5.6 +/- 3.0 arcsec in Az., 3.1 +/- 2.5 arcsec in El., and -0.6 +/- 0.6 mm for focus (stable and close to the nominal values after the intervention of PT100 sensors by Salvador Sánchez in the afternoon). Pointing and focus correction on NGC7027. A set of calib_1scan maps were obtained on that source (20220110s181), MWC349 (s182), and CRL2688 (s183). Very stable at the end of the shift. Coming back to Uranus. Resonances were reworked before pointing and a new focus correction. Beam map (h option) on Uranus (s198).
