| 04h30; Ángel: Opacity (tau[225 GHz]) above 0.5, with some spikes up to 0.95 during the shift. First pointing and focus on Mars (low altitude). Beam sizes a bit broadened: ~14.5", 18.5", 14.3"; ToD +/-2 Jy/b, rms ~146 mJy/b (2mm). Focus and pointing on 1226+023 and then on 1156+295 (close to the science target). Monitoring opacity and stability before starting science observations, looking at the beam geometry too. At 23:30 it was decided to start the observations of UDG584 field (E03-20). A total of 7 repetitions (24 min. each) were gathered, starting with fluctuations in time of +/-2 Jy/b at 2 mm and +/-5 Jy/b at 1 mm. Mean rms of ~55 mJy/b at 2 mm. Stopped at 03:20 when the target was close to El.=30 deg. Then a skydip (s29) was tried: too large variation of NIKA2 taus, barely valid. Secondary flux standards MWC349 (s37) and NGC7027 (s39) observed with calib_1scan routine (beam sizes: 12.8", 17.5", 12.9"). EMIR Pool observations continued after 04:30. | 05h10; Ángel: Opacity (tau[225 GHz] from radiometer) about 0.4, relatively stable. NIKA2 pointing model set to Winter. Bad kids, total kids after new sweep and start acquisition (window open): 22, 1055 (arr1); 5, 573 (arr2); 33, 1056 (arr3). Some problems at the beginning with imbfits creation in ~/mnt/data/NIKAIMBFITS/current/. Fixed: OK. Setting to project nikas-21. Pointing on W3OH. Corrupted file/synchro problems message from piic-monitor2pf (due to kids geometry changes, I guess). IDL pipeline configured to run66 instead of run67. Adopting pointing 0.,0. and focus -0.8. Beammap on Uranus (scan 34). Slight opacity spike in the middle. Ephemeris fluxes from ASTRO: 19.1 Jy/b (150 GHz) and 44.9 Jy (260 GHz). Then a skydip (scan 35). Changing focus to -1.0. A second beammap on Uranus was tried at 07h50 (scan 38) with a mean opacity ~0.5 +/- 0.1. End of time agreed. Additional notes in TAPAS. |
