Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the 6cm NME and ftp fringe-test on 09 March 2022 involving the following antennas: Jb2, Wb, Ef, Mc, Nt, On85, T6, Ur, Tr, Ys, Hh, Sv, Zc, Bd, Ir, Km, Cm, Da, De, Pi, Kn The NME uses a standard setup with 2048 Mbps. The schedule consists of long integrations on calibrators J0319+4130 and J0530+1331 for ftp-fringe tests. We will use J0528+1347 for phase-referencing check. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:15:00 (scan 2, 2 sec, J0319+4130) 12:45:00 (scan 4, 2 sec, J0530+1331) 13:15:00 (scan 8, 2 sec, J0530+1331) 13:45:00 (scan 12, 2 sec, J0530+1331) 14:15:00 (scan 16, 2 sec, J0530+1331) 14:45:00 (scan 20, 2 sec, J0530+1331) Good luck with the session!
