Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the 6cm NME and ftp fringe-test on 25 Feb 2024 involving the following antennas: Jb1, Wb, Ef, Mc, On85, T6, Ur, Tr, Ys, Hh, Ir, Sr, Cm, Da, De, Pi, Kn The NME uses a standard setup with 4096 Mbps. The schedule consists of long integrations on the awesome, iconic 3C84 for ftp-fringe tests. We will use J0316+4119 for phase-referencing check. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:15:00 (scan 2, 2 sec, 3C84) 12:45:00 (scan 4, 2 sec, 3C84) 13:15:00 (scan 8, 2 sec, 3C84) 13:45:00 (scan 12, 2 sec, 3C84) 14:15:00 (scan 16, 2 sec, 3C84) 14:45:00 (scan 20, 2 sec, 3C84) Good luck with the session!
