Code: N20M3 Schedule Version: 1.00 Processed by SCHED version: 11.60 Release 11.6; April 2020 PI: Olga Bayandina Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596507 EMAIL: bayandina@jive.eu Fax: Phone during observation: +31-521-596507 Observing mode: Notes: 5cm NME and ftp fringe test for Session 3 2020 (256 Mbps, L+R, 2-bit sampling, 4 MHz filters; with a 2Gbps mode via 32 MHz filters at the end) COVER LETTER: This is the schedule for the 5cm NME and ftp fringe-test on 2020, October 15 involving antennas: Jb2, Wb, Ef, Mc, Nt, On85, T6, Tr, Ys, Ir, Sr, Km, Cm, Da, De, Kn, Pi. The NME uses a standard setup with 256 Mbps (and 2Gbps mode at the end); both as will follow in user experiments. The schedule consists of long integrations on calibrators 3C345, J2031+1219, and J2139+1423 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 256 Mbps 12:18:00 (scan 2, 2 sec, 3C345) 12:38:00 (scan 4, 2 sec, 3C345) 12:58:00 (scan 6, 2 sec, 3C345) 13:18:00 (scan 8, 2 sec, J2031+1219) 13:38:00 (scan 10, 2 sec, J2031+1219) 13:58:00 (scan 12, 2 sec, J2031+1219) 2Gbps 14:18:00 (scan 14, 2 sec, J2139+1423) 14:38:00 (scan 16, 2 sec, J2139+1423) 14:58:00 (scan 18, 2 sec, J2139+1423) Good luck with the session!
