Arecibo may join after 14:55UT. The NME uses a standard setup with 512 Mbps. The schedule consists of long integrations on calibrators J1014+2301 and J0336+3218 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 13:15:00 (scan 2, 2 sec, J1014+2301) 13:45:00 (scan 4, 2 sec, J1014+2301) 14:15:00 (scan 6, 2 sec, J1014+2301) 14:45:00 (scan 8, 2 sec, J1014+2301) 15:15:00 (scan 10, 2 sec, J0336+3218) --- Arecibo joins 15:45:00 (scan 12, 2 sec, J0336+3218) 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) J0336+3218 19.4 J1014+2301 73.2 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.
