Code: F13K2 Schedule Version: 1.00 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: K-band ftp test for session 3/2013 1 Gbps, 2-bit sampling, 16 MHz filters COVER LETTER: Dear EVN friends, This is the schedule for the K-band ftp fringe-test on 16 October 2013, involving 15 antennas: Eb Jb2 On20 Mc Nt Tr Mh Sv Zc Bd Ur Sh KVNYS KVNUS KVNTN. Stations testing their new DBBC backends are also included, with different names: MC_DBBC and TR_DBBC. The ftp test uses a setup with 1 Gbps and consists of long integrations on standard fringe finder calibrators: 3C345 (2 Jy at 22 GHz) and J1800+3848 (0.6 Jy at 22 GHz). There are two ftp fringe-test scans (1) 12:09:00 UT (scan 2, 2 sec, 3C345) (2) 12:45:00 UT (scan 6, 4 sec, J1800+3848) Please make sure that the autoftp is set up correctly. See you on Skype group chat and Good luck with the session!

The distance from the Sun to each source in this schedule is: Source Sun distance (deg) 3C345 66.8 J1800+3848 79.5 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz.
