The schedule consists of long integrations on calibrators J0927+3902 and J1224+2122 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 14:15:00 (scan 2, 2 sec, J0927+3902) 14:45:00 (scan 4, 2 sec, J0927+3902) 15:15:00 (scan 6, 2 sec, J0927+3902) 15:45:00 (scan 8, 2 sec, J1224+2122) 16:15:00 (scan 10, 2 sec, J1224+2122) 16:45:00 (scan 12, 2 sec, J1224+2122) 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) J0927+3902 61.5 J1224+2122 103.2 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.
