PI: Yurii Pidopryhora Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596548 EMAIL: pidopryhora@jive.nl Fax: Phone during observation: +31-521-596548 Observing mode: Notes: COVER LETTER: This is the schedule for the C-band ftp fringe-test on 07 March 2012 involving 12 (13)* antennas: Ef Wb (Jb1)* On Mc Tr Ys Sv Zc Bd Ur Sh Hh * It is possible that Lovell will participate. The ftp test uses a standard setup and consists of long integrations on a strong source 0234+285 - a standard fringe finder. Three ftp tests are scheduled: ~12:09 UT (scan 2, 4 sec, 0234+285) ~12:30 UT (scan 4, 4 sec, 0234+285) ~12:51 UT (scan 6, 4 sec, 0234+285) Please make sure that the autoftp is set up correctly. Good luck with the session! Yurii Schedule for SHANGHAI (Code Sh ) Page 2 Ftp test UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up. Early: Seconds between end of slew and start. Dwell: On source seconds. Disk: GBytes recorded to this point. TPStart: Recording start time. Frequencies are LO sum (band edge).

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) 0234+285 59.8 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.
