COVER INFORMATION Station: URUMQI (Code Ur ) Experiment: Network Monitoring Experiment Exp. Code: N13L3 Schedule Version: 1.00 Processed by SCHED version: 10.20 Release of about July 12, 2012 PI: Ivan Agudo Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596549 EMAIL: agudo@jive.nl Fax: Phone during observation: +31-521-596549 Observing mode: Notes: 18cm NME for session 3/2013 512 Mbps, 2-bit sampling, 8 MHz filters Send the disk pack by express to JIVE Additional DBBC testing data from Mc and Tr is expected. COVER LETTER: Dear EVN friends, This is the schedule for the 18cm NME on October 27 2013, involving 14 stations: Eb Wb Jb1 On25 Mc Nt Tr Sv Zc Bd Ur Sh Hh Ir The NME uses a standard setup with 512 Mbps and consists of four ftp fringe tests, interspersed with a long phase referencing cycle involving 2201+315 (4C+31.63, ~2 Jy source at 1.4 GHz) and a close position reference calibrator (J2157+3127, ~0.44Jy in S band and ~1.27deg away). The four ftp fringe-test scans, all of them on 2201+315, start at: (1) 13:12:30 UT (scan 4, 2 sec) (2) 14:15:30 UT (scan 17, 2 sec) (3) 15:23:00 UT (scan 31, 2 sec) (4) 15:52:30 UT (scan 37, 2 sec) See you on Skype group chat and Good luck with the session!
