COVER LETTER: This is the schedule for the 6cm NME and ftp fringe-test on 31st May 2024 involving the following (10) antennas: Jb2 Wb1 Ef Mc On85 Tr Ys Hh Ir Sr The NME uses a standard setup with 4096 Mbps. The schedule consists of long integrations on the calibrator J0854+2006. We shall use J0905+2052 in one scan for phase referencing check purposes. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:10:00 (scan 2, 2 s, J0854+2006) 12:40:00 (scan 4, 2 s, J0854+2006) 13:10:00 (scan 6, 2 s, J0854+2006) 13:40:00 (scan 8, 2 s, J0854+2006) 14:10:00 (scan 10, 2 s, J0854+2006) 14:40:00 (scan 12, 2 s, J0854+2006) 14:58:00 (scan 16, 2 s, J0854+2006) Good fringes to everyone!
