COVER INFORMATION Station: ZELENCHK (Code Zc ) Experiment: Network Monitoring Experiment Exp. Code: N14C3 Schedule Version: 1.00 Processed by SCHED version: 11.00 Release of Feb. 15, 2013 PI: Ciriaco Goddi Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596548 EMAIL: goddi@jive.nl Fax: Phone during observation: +31-521-596548 Observing mode: Notes: 6cm NME and 4 ftp fringe test for session 2/2014 512 Mbps, L+R, 2-bit sampling, 16 MHz filters Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the 6cm NME and ftp fringe-test on 22 Oct 2014 involving 12 antennas: Eb Wb Jb1 On25 Nt Tr Sv Zc Bd Sh Hh Ys. The NME uses a standard 512 Mbps setup. The schedule consists of: - long integrations on strong calibrators (3C345, 1848+283, 2023+336) for ftp-fringe tests; - phase-reference cycles with continuum sources (J1640+3946 and J1849+3024) as targets. Three ftp-fringe tests are scheduled throughout the experiment: 12:09:00 (scan 2, 2 sec, 3C345) 13:20:20 (scan 37, 2 sec, 1848+283) 14:29:00 (scan 72, 2 sec, 2023+336) Please make sure that the autoftp is set up correctly. Thanks! See you on Skype group chat and Good luck with the session!
