Weather was again quite poor with rain and wind. Effelsberg had also some pointing issues, the antenna was more than half a beam off source (20 to 25 arcsec) until 7:45 UT. The beam size is 36 arcsec.

No known problem.

Onsala (Jun Yang at Mon Mar 19 10:12:58 2018) Success:

The Chopper-wheel calibration was used. Because of the slightly longer processing time of the hot load in and out, the first 3-6 seconds data at the scan beginning were affected and had high Tsys (flagged out already in the antabfs file). So, these related data should be flagged out in the post data reduction. Note that the Tsys data were opacity-corrected (optical depth: 0.2-0.3).
