COVER INFORMATION Station: EFLSBERG (Code Ef ) Experiment: Network Monitoring Experiment Exp. Code: N14C3 Schedule Version: 1.00 Processed by SCHED version: 11.00 Release of Feb. 15, 2013 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: 6cm NME and 4 ftp fringe test for session 2/2014 512 Mbps, L+R, 2-bit sampling, 16 MHz filters Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the 6cm NME and ftp fringe-test on 22 Oct 2014 involving 12 antennas: Eb Wb Jb1 On25 Nt Tr Sv Zc Bd Sh Hh Ys. The NME uses a standard 512 Mbps setup. The schedule consists of: - long integrations on strong calibrators (3C345, 1848+283, 2023+336) for ftp-fringe tests; - phase-reference cycles with continuum sources (J1640+3946 and J1849+3024) as targets. Three ftp-fringe tests are scheduled throughout the experiment: 12:09:00 (scan 2, 2 sec, 3C345) 13:20:20 (scan 37, 2 sec, 1848+283) 14:29:00 (scan 72, 2 sec, 2023+336) Please make sure that the autoftp is set up correctly. Thanks! 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) J1640+3946 64.8 3C345 65.2 J1849+3024 83.4 1848+283 83.1 2023+336 103.9 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.
