COVER INFORMATION Station: MC_DBBC (Code Md ) Experiment: Network Monitoring Experiment Exp. Code: N13C2 Schedule Version: 2.00 Processed by SCHED version: 10.20 Release of about July 12, 2012 PI: Dmitry Duev Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596549 EMAIL: duev@jive.nl Fax: Phone during observation: +31-521-596549 Observing mode: Notes: 6cm NME and ftp fringe test for session 2/2013 (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 24 May 2013 involving 15 antennas: Eb Wb Jb1 On25 Mc Nt Tr Ys Sv Zc Bd Ur Sh Hh Ir (Jm Od Nd Md Td 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. Three ftp-fringe tests are scheduled throughout the experiment: ~08:07:58 (scan 2, 2 sec,0234+285) ~09:03:56 (scan 15, 2 sec, DA193) ~09:57:58 (scan 27, 2 sec, DA193) Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session! Dmitry Schedule for MC_DBBC (Code Md ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.
