COVER INFORMATION Station: SHANGHAI (Code Sh ) Experiment: NME + FTP FT Exp. Code: N14C1 Schedule Version: 3.00 Processed by SCHED version: 11.00 Release of Feb. 15, 2013 PI: Ivan Agudo Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596-549 EMAIL: agudo@jive.nl Fax: Phone during observation: +31-521-596-549 Observing mode: Notes: 6cm NME + FTP FT for session 1/2014 512 Mbps, 2-bit sampling, 8 MHz filters Participation from Sr (with DBBC), and Sh65 (TIANMA65 or T6) expected Additional DBBC testing data from Mc, Tr, and Ys is also expected. COVER LETTER: Dear EVN friends, This is the schedule for the 1.3cm FTP-FT on March 04 2014, involving 19 stations: Eb Wb Jb1 On25 Mc Nt Tr Sv Zc Bd Ir Ur Sh Hh Ys, as well as Md Td Yd (Mc Tr and Ys with DBBC) and Sh65. The session uses a standard setup with 512 Mbps and consists of three ftp fringe tests, interspersed with a longer set of phase referencing scans on 3C 84 (~25 Jy source at 5 GHz), and a weaker calibrator. The three ftp fringe-test scans, start at: (1) 14:07:30 UT (scan 2, 2 sec) (2) 14:57:20 UT (scan 20, 2 sec) (3) 16:52:50 UT (scan 62, 2 sec) See you on Skype group chat and Good luck with the session!

SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) J0313+4120 74.7 3C84 76.0 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.
