Summary for Onsala for Session 2014-2

Experiment End date Friend Result Problem Text
EC0442014-06-17Jun YangMinor failuresANTThe fuse associated with the Declination motor was blew again at night. The exact time was at ~0:40 UT. After that, the antenna could only track the calibrator J1925+2106. The observations stopped at 3:40 UT when the operator noticed the problem.
EC0482014-06-02Jun YangSuccessNoneNo known problems.
EG078B2014-06-06Jun YangSuccessSCHEDThere were some warning messages (once per 30 min) because the procedure setup01 tried to change recording setup during a short gap (10s). This should be avoided in the future.
EH0312014-06-04Jun YangSuccessNoneNo known problems.
EL048A2014-06-03Jun YangSuccessNoneOther than RFIs, no known problems.
EL048B2014-06-11Jun YangSuccessNoneThere were some transient MK5 communication timeout problems during the observations.
EL048B2014-06-11Jun YangSuccessNoneThere were some transient MK5 communication timeout problems during the observations.
EL051A2014-05-30Jun YangSuccessNoneNo known problems.
EL051B2014-06-12Jun YangSuccessNoneStowed antenna at 3 UT due to high wind.
EP087G2014-05-29Jun YangSuccessNoneNo known problems.
EP087H2014-06-09Jun YangSuccessNoneNo known problems.
EP088E2014-06-02Jun YangSuccessNoneRFIs at 1687.5 MHz.
EP088F2014-06-10Jun YangSuccessNoneNo known problems.
ER035B2014-06-19Jun YangSuccessNoneNo known technical problems. The Tsys data were quit high. Note that the atmospheric opacity was already corrected in the log and antabfs files as Chopper wheel calibration was used. The average opacity was 0.49 during the experiment.
ES072H2014-06-13Jun YangFailureNoneNo observation due to strong winds.
ES072I2014-06-14Jun YangSuccessNoneNo known problems during the observations.
ES072J2014-06-15Jun YangSuccessNoneNo known problems.
ES072K2014-06-16Jun YangFailureANTNo observations because three fuses were broken on the same day and there might be some deep problem in the system.
ES074A2014-06-18Jun YangSuccessNoneIt was a blue sky day. No known problems.
ES074A2014-06-18Jun YangSuccessNoneNote that atmospheric opacity was corrected in the Tsys data of log and antabfs files at Onsala. The average opacity along the source direction was 0.26 during the experiment.
F14C22014-06-09Jun YangSuccessNoneSuccess
F14L22014-05-29Jun YangSuccessNoneNone
F14M22014-06-12Jun YangSuccessNoneNo known problems.
GA032B2014-06-07Jun YangSuccessNoneThe weather was quite good (no rain, nor clouds) for the observations.
GB075A2014-06-08Jun YangSuccessNoneAgain, it was a perfect day for the 7mm VLBI observations. There were no any problems found in the log files.
GP051A2014-06-12Jun YangSuccessNoneQuite windy. The wind speed was ~12 m/s, fortunately still below the acceptable limit (13 m/s).
GP051C2014-06-14Jun YangSuccessNoneNo known problems.
GP051D2014-06-15Jun YangFailureNoneAfter the first scan, the fuse associated with the declination motor was broken. A new fuse was re-installed and broken again in a short time. The telescope engineer suggested to stow the telescope and do a deep check later on the upcoming Monday. No really useful data in the disks.
N14C22014-06-10Jun YangSuccessNoneSuccess with fringes.
N14K22014-06-17Jun YangSuccessNoneClearly fringes were found in the ftp fringe tests.
N14K22014-06-17Jun YangSuccessNoneTsys data in the log and antabfs files were opacity free. The average opacity during the experiment was 0.33.
N14L22014-06-02Jun YangSuccessNoneNo problems.
N14M22014-06-13Jun YangSuccessNoneFringes were found in the FTP fringe tests.
N14Q12014-06-06Jun YangSuccessNoneSuccess with ftp fringes although the weather was poor (cloudy and raining at the beginning).
