COVER INFORMATION Station: EFLSBERG (Code Ef ) Experiment: Network Monitoring Experiment Exp. Code: N15M2 Schedule Version: 2.00 Processed by SCHED version: 11.40 Release 11.4. March 14, 2015 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 3 ftp fringe test for session 3/2015 (128 Mbps, L+R, 2-bit sampling, 2 MHz filters) Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the 5cm NME and ftp fringe-test on 21 October 2015 involving 10 antennas: Eb Wb1 Jb2 Mc On8 Nt Tr Ys Sr Ir. The NME uses a standard setup with 128 Mbps. The schedule consists of: - long integrations on strong calibrators like DA193, J0927+3902, and 3C345 for ftp-fringe tests; - linear polarization check using the polarized calibrators J0927+3902 and 3C286; - D-terms check using the calibrators DA193 and 3C345; - and phase-referencing parts with a continuum source (0548+378 and J1640+3946) as target. Three ftp-fringe tests are scheduled throughout the experiment: 09:09:58 (scan 2, 2 sec, DA193) 10:11:58 (scan 35, 2 sec, J0927+3902) 11:53:13 (scan 72, 2 sec, 3C345) Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session!
