COVER INFORMATION Station: URUMQI (Code Ur ) Experiment: Network Monitoring Experiment Exp. Code: N16C1 Schedule Version: 4.00 Processed by SCHED version: 11.40 Release 11.4. March 14, 2015 PI: Benito Marcote Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596508 EMAIL: marcote@jive.eu Fax: Phone during observation: +31-521-596508 Observing mode: Notes: 6cm NME and ftp fringe test for session 1/2016 (512 Mbps, L+R, 2-bit sampling, 2 MHz filters) Please send the disk pack by express to JIVE v.4 includes parallel-testing Ys/Yd (fila10G+vdif) COVER LETTER: This is the schedule for the 6cm NME and ftp fringe-test on 18 February 2016 involving 14 antennas: Jb2 Wb1 Ef Mc Nt On8 Sh T6 Ur Tr Ys Sv Zc Bd. The NME uses a standard setup with 512 Mbps. The schedule consists of: - long integrations on strong calibrators like 3C84 and J0418+3801 for ftp-fringe tests; Four ftp-fringe tests are scheduled throughout the experiment: 12:09:58 (scan 2, 2 sec, 3C84) 13:04:58 (scan 8, 2 sec, 3C84) 13:59:58 (scan 14, 2 sec, J0418+3801) 14:44:58 (scan 19, 2 sec, J0418+3801) Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session!
