The schedule consists of long integrations on strong calibrators (0234+285 & 3C84) for ftp-fringe tests. At 18cm, 0234+285 is ~1.3 Jy/beam and 3C84 is ~10.4Jy/beam) Four ftp-fringe tests are scheduled throughout the experiment: 12:09:00 (scan 2, 2 sec, 0234+285, all ants) 12:54:00 (scan 8, 2 sec, 3C84, Hh ~20deg) 13:39:00 (scan 14, 2 sec, 0234+285, Sh & T6 ~15deg) 14:24:00 (scan 20, 2 sec, 3C84, no Zc; Sh, T6, Hh ~20deg) All antennas will participate in at least two FTP fringe tests. Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session and see you on Skype!

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 63.6 3C84 76.5 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.
