The schedule consists of long integrations on the strong calibrators J1058+0133 and J1159+2914, for ftp-fringe tests; and the sources J1152+2930 and J1221+2813 will be observed for phase-referencing test purposes. Seven ftp-fringe tests are scheduled throughout the experiment: 14:10:00 (scan 1, 4 sec, J1058+0133) 14:40:00 (scan 3, 4 sec, J1058+0133) 15:10:00 (scan 5, 4 sec, J1159+2914) 15:40:00 (scan 7, 4 sec, J1159+2914) 16:10:00 (scan 9, 4 sec, J1159+2914) 16:35:00 (scan 15, 4 sec, J1159+2914) 16:58:00 (scan 21, 4 sec, J1159+2914) Good luck with the session!
