Nevertheless we take the risk. We had a sure fringe detection for all scans at all baselines except one observation. Observed SNR is presented in this table. Time here is a reference time tag. These data are gathered in another table.
Time tag is the time of the start of the scan.
We see that there is strong signal in all stations which observed opposite polarization. Phases are in radians, time is in hours elapsed from the start of the session. Those who understands magic of fringe plots may find interesting to look at some fringe plots of the cross-polarization scans. Change of polarization during experiment caused a jump in phase calibration phases what was predictable since signal traveled another path. Fringe amplitude between adjacent channels were also not aligned.
