COVER INFORMATION Station: YEBES40M (Code Ys ) Experiment: Network Monitoring Experiment Exp. Code: N14K1 Schedule Version: 2.00 Processed by SCHED version: 10.20 Release of about July 12, 2012 PI: Ciriaco Goddi Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596548 EMAIL: goddi@jive.nl Fax: Phone during observation: +31-521-596548 Observing mode: Notes: 1.3 cm NME for session 1/2014 1 Gbps, 2-bit sampling, 16 MHz filters Send the disk pack by express to JIVE COVER LETTER: Dear EVN friends, This is the schedule for the 1.3cm NME on March 11 2014, involving 16 EVN antennas: Eb Jb2 On20 Mc Nt Tr Sv Zc Bd Ur Sh Sh65 Hh Ys Mh Sr, plus the KVN stations KVNYS KVNUS KVNTN. Stations testing their new DBBC backends are also included: MC_DBBC (Md), TR_DBBC (Td), and YS_DBBC (Yd). The NME uses a setup with 1 Gbps and consists of integrations on the VLBI fringe finder DA193 (~1.8Jy at 22 GHz) as well as phase-referencing cycles between continuum calibrators (1st phase-reference cycle: J2040+4527 -- J2039+4159; 2nd phase-reference cycle: DA193 -- J0605+4030). There are three ftp fringe-test scans (1) 14:09:00 UT (scan 2, 2 sec, DA193) (2) 15:31:00 UT (scan 38, 2 sec, DA193) (3) 16:29:00 UT (scan 69, 2 sec, DA193) See you on Skype group chat and Good luck with the session!
