COVER INFORMATION Station: JODRELL1 (Code Jb ) Experiment: Network Monitoring Experiment Exp. Code: N13C1 Schedule Version: 2.00 Processed by SCHED version: 10.20 Release of about July 12, 2012 PI: Gabriele Surcis Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596508 EMAIL: surcis@jive.nl Fax: Phone during observation: +31-521-596508 Observing mode: Notes: 6cm NME and ftp fringe test for session 1/2013 (512 Mbps, L+R, 2-bit sampling, 8 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 25 February 2013 involving 15 antennas: Eb Wb Jb1 On25 Mc Nt Tr Ys Sv Zc Bd Ur Sh Hh Ir (Jm Od Nd Yd Hd). The NME uses a standard setup with 512 Mbps and consists of long integrations on strong calibrators like 0234+285 and DA193 as well as phase-referencing parts with a continuum source as target. The schedule also include an additional wb-test scans after the regular NME. The involved antennas are Wb, Tr, Ys, and On (Yd and Od). There will be a ftp-fringe test for each scan. Three ftp-fringe tests are scheduled throughout the experiment: ~14:07:58 (scan 2, 2 sec,0234+285) ~15:03:56 (scan 15, 2 sec, DA193) ~15:57:58 (scan 27, 2 sec, DA193) Four ftp-fringe extra tests are schedules for (Wb, Tr, Ys, and On) first ftp (scan=28) starts 16:09:56 ends 16:10:00 second ftp (scan=29) starts 16:18:56 ends 16:19:00 third ftp (scan=30) starts 16:28:56 ends 16:29:00 fourth ftp (scan=31) starts 16:38:56 ends 16:39:00 Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session!
