Four ftp tests are scheduled: ~11:09 UT (scan 2, 2 sec, 0234+285) ~11:30 UT (scan 4, 2 sec, 0234+285) ~11:51 UT (scan 6, 2 sec, 0234+285) ~11:51 UT (scan 8, 2 sec, 0234+285) Please make sure that the autoftp is set up correctly. Good luck with the session! Ciriaco Schedule for EFLSBERG (Code Ef ) Page 2 Ftp test UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.

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 59.0 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.
