There is no phase referencing section in this experiment. Four ftp tests are scheduled: ~12:08:40 UT (scan 2, 4 sec, 4C39.25) ~12:57:30 UT (scan 8, 4 sec, 4C39.25) ~13:44:10 UT (scan 13, 4 sec, J1043+2408) ~14:45:40 UT (scan 20, 4 sec, J1043+2408) Please make sure that the autoftp is set up correctly.
