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. For common VLBI bands, this is: 327 MHz 117. deg 610 MHz 81. deg 1.6 GHz 45. deg 2.3 GHz 36. deg 5.0 GHz 23. deg 8.4 GHz 17. deg 15.0 GHz 12. deg 22.0 GHz 9. deg 43.0 GHz 6. deg
