COVER INFORMATION Station: JODRELL1 (Code Jb ) Experiment: Network Monitoring Experiment Exp. Code: N15C1 Schedule Version: 2.00 Processed by SCHED version: 11.30 Version 11.3 update 1. April 14, 2014 PI: Dmitry Duev Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596521 EMAIL: duev@jive.nl Fax: Phone during observation: +31-521-596521 Observing mode: Notes: 6cm NME and 4 ftp fringe test for session 1/2015 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 4 Mar 2015 involving 14 antennas: Eb Wb Jb1 On85 Mc Nt Tr Sh Ur Sv Zc Bd Hh Ys. The NME uses a standard 512 Mbps setup. The schedule consists of: - long integrations on strong calibrators (3C84, 0234+285, DA193) for ftp-fringe tests; - phase-reference cycles with a continuum source (J0225+2955) as a target. Three ftp-fringe tests are scheduled throughout the experiment: 12:09:00 (scan 2, 2 sec, 3C84) 13:23:40 (scan 19, 2 sec, 0234+285) 14:34:00 (scan 38, 2 sec, DA193) Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session and see you on Skype!
