Summary for Onsala for Session 2014-1

Experiment End date Friend Result Problem Text
EA053A2014-03-04Jun YangMinor failuresNoneThe internet connection was broken from 10:05 UT to 11:22 UT. There were no valid data, nor communication with the telescope during the time range.
EA053B2014-03-05Jun YangSuccessNoneNo wind, nor rain. The whole observing system performed as expected. No any known problems.
EA053C2014-03-05Jun YangSuccessNoneNo known problems.
EA053D2014-03-06Jun YangSuccessNoneBecause of wind, antenna could not maintain good pointing at a certain time. The message of antenna off-source (offset > 100 arcsec) and re-acquired were seen frequently. Applying uvflgfs file will flag out these data during each scan.
EF0252014-02-22Jun YangSuccessNoneIt was a cloudy day, while the experiment was successfully done in the e-EVN mode.
EG062E2014-03-05Jun YangSuccessNoneThe observations ran smoothly. No rain. Wind speed was low.
EG062F2014-03-06Jun YangSuccessNoneNo known problems.
EG062F2014-03-06Jun YangSuccessNoneNo known problems.
EG080A2014-02-27Jun YangSuccessNoneNone
EG080B2014-03-10Jun YangSuccessNoneNo known problems.
EH028B2014-02-24Jun YangMinor failuresNoneNo observations after 13:10 UT because of strong (>13.2 m/s) winds. Due to RFI, Tsys measurements in BBC 4 and 8 were significantly affected.
EM1102014-02-26Jun YangSuccessNoneNone
EM1112014-02-20Jun YangSuccessNoneRaining almost all the time and getting quite windy at the end of the experiment.
EP088C2014-02-24Jun YangSuccessNoneCloudy day.
EP088D2014-03-04Jun YangSuccessNoneCloudy, while no rain. Because of wind, the 25m antenna could not maintain a good pointing and frequently reported the message of off-source (offset > 100 arcsec). The uvflgfs file should be applied carefully.
ES071B2014-02-28Jun YangSuccessNoneTsys increased significantly (2-4x) after 12:30 UT likely associated with the bad weather (rain).
ES072E2014-03-01Jun YangSuccessNoneTsys went up and down due to rain.
ES072F2014-03-02Jun YangSuccessNoneNone
ES072G2014-03-03Jun YangMinor failuresANTDue to a problem with the antenna control/communication hardware, the 25m antenna could not track sources any more after 9:27 UT.
EV019A2014-02-25Jun YangMinor failuresNoneQuite windy. Because of wind, the 25m telescope pointing can not be well maintained and there were many "off-source" messages during scans. Please apply the uvflgfs file carefully during the post data reduction.
EV019B2014-03-07Jun YangSuccessNoneBecause of wind, antenna could not well track the source. If the Onsala uvflg file is applied, the data with a pointing offset >100 arcsec during the scan will be flagged out.
EV019B2014-03-07Michael LindqvistSuccessNoneTo low elevation first scans.
F14C12014-03-03Jun YangSuccessNoneNone
F14K12014-03-10Jun YangSuccessNoneNo known problems.
F14L12014-02-20Jun YangMinor failuresNoneNo recording during the first 13 minutes due to a drudge error (e-vlbi mode).
F14M12014-02-27Jun YangSuccessNoneNone
GA032A2014-03-11Jun YangSuccessNoneThe e-VLBI fringes on the calibrators were clearly seen during the science part.
GP053A2014-03-05Jun YangSuccessNoneNo known problems.
N14C12014-03-04Jun YangSuccessNoneNo known problems.
N14K12014-03-11Jun YangSuccessNoneThanks to the great weather (blue sky), Onsala sensitivity was quite good.
N14L12014-02-26Jun YangSuccessNoneNone
N14M12014-03-01Jun YangSuccessNoneNone
EA053E2014-03-09NoneNoneNoneNone
