The schedule consists of long integrations on calibrator J0804+2006. We shall use J0905+2052 for phase referencing. We will also use a single scan on J0806+4504 for the flux calibration of e-MERLIN stations. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:13:00 (scan 2, 2 sec, J0804+2006) 12:35:00 (scan 4, 2 sec, J0804+2006) 13:05:00 (scan 6, 2 sec, J0804+2006) 13:35:00 (scan 10, 2 sec, J0804+2006) 14:05:00 (scan 14, 2 sec, J0804+2006) 14:35:00 (scan 18, 2 sec, J0804+2006) Happy C-inging!
