| 15:45-21:00; Angel: DAQ started and tuning | 15:45-21:00; Angel: DAQ started and tuning with 48/7/54 bad kids for Ar1/Ar2/Ar3. No evidence of correlated spikes in the noise spectra for all arrays. Tau(225 GHz) between 0.20 and 0.25 throughout the shift with some spikes. Pointing on Uranus (1.5, -11.6), larger in elevation than expected. NIKA2 mirrors deployment re-checked. Best focus -1.0 mm. Pointing corrections are stable at this position. Beam sizes: 12.9"/18" because of a slight ellipticity. Good atmosphere stability: ~2 Jy/b at 2 mm. Checking pointing corrections (6 values) in ~70 < Az. < 120 deg, and ~45 < El. < 70 deg. We get corrections <Az.> = 3.2 +/- 1.4 and <El.> = -8.9 +/- 3.0. Refocusing and checking stability (~1-2 Jy/b at 2 mm). Science observations started with project 110-21 (2 reps. on NGC1333-C7). Then, 2 reps. on B213E (GASTON). More stable after sunset. The shift was finished with the observation of target WB89-793 of project 137-21. |
