Daily Reports
Feb. 13th, Tuesday
10:30-15:00; Maintenance slot.
15:00-16:30; System check with EMIR (Joaquín Santiago); Jean's tests of the BluePill and Aleksej's tests of the wobbler system (both in remote).
16:30-21:00; Jianhang, Stefano, Antoine, Federico, Angel: tau_225GHz~0.5, wind speed about 2-4 m/s, not so stable atmosphere, but after pointing & focus trials, look quite good for EMIR backup programs. Some problems with beam switching (not-so-good behaviour of the chopper wheel; fixed provisionally by launching two pointings in a row per pointing try). We started with EMIR backup program 073-23, TMC2 and CB23 were successfully observed. At ~20h we switched to project 104-23. The first map set for target W3-IRS5 (2h) was started. InSegment tracking deviations below 1 arcsec. At 19:52 (UT) a continuous sequence of TCP/IP local socket closed/connected messages in the PCP started to appear. The queue was cancelled by Juan Luis. After the due error acknowledgment in the PCP, we launched a calibration. No more warning/error rolling messages in the PCP.
21:00-03:00; Jianhang: The observation of the first map set for target W3-IRS5 (project 104-23) was resumed by completing the scans removed from the queue before. Switched to project 152-23: line calibration on M82, REF position checked, and 5 repetitions on J0826. Mean tau_225GHz increasing up to ~0.6 with large spikes over most of the shift, very low wind speed. Light fog outside at the end of the shift.
