COVER INFORMATION Station: NT_DBBC (Code Nd ) Experiment: Network Monitoring Experiment Exp. Code: N13M1 Schedule Version: 3.00 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: 5cm NME and ftp fringe test for session 1/2013 (512 Mbps, L+R, 2-bit sampling, 2 MHz filters) Please send the disk pack by express to JIVE Please DO NOT use the phase cal signal. COVER LETTER: This is the schedule for the 5cm NME and ftp fringe-test on 28 February 2013 involving 9 antennas: Eb Wb1 Jb2 On25 Mc Nt Tr Ys Hh (Jm, Od, Nd, Yd, Hd). The NME uses a standard setup with 512 Mbps. The schedule consists of long integrations on strong calibrators like 0528+134 as well as phase-referencing parts with a continuum source as targets. Three ftp-fringe tests are scheduled throughout the experiment: 15:09:58 (scan 2, 2 sec, 0528+134) 16:08:56 (scan 19, 4 sec, 0528+134) 16:52:56 (scan 34, 4 sec, 0528+134) Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session!
