The schedule consists of long integrations on calibrators J0319+4130 and J0646+4451 for ftp-fringe tests. We shall use J0654+4347 for phase referencing. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 08:00:00 (scan 1, 2 sec, J0319+4130) 08:30:00 (scan 3, 2 sec, J0319+4130) 09:00:00 (scan 5, 2 sec, J0319+4130) 09:30:00 (scan 9, 2 sec, J0646+4451) 10:00:00 (scan 13, 2 sec, J0646+4451) 10:30:00 (scan 17, 2 sec, J0646+4451) Happy C-ing!
