The experiment uses a standard setup with 512 Mbps and consists of long integrations on strong calibrators DA193 and 2251+158. Four ftp tests are scheduled: (1) 10:38:58 UT (scan 2, 2 sec, 2251+158) (2) 10:54:58 UT (scan 4, 2 sec, DA193) (3) 11:09:58 UT (scan 6, 2 sec, 2251+158) (4) 11:20:58 UT (scan 7, 2 sec, DA193) Please make sure that the autoftp is set up correctly. 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) DA193 18.7 2251+158 88.7 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.
