Three ftp tests are scheduled: ~11:09 UT (scan 2, 2 sec, 0234+285) ~11:30 UT (scan 4, 4 sec, 0234+285) ~11:51 UT (scan 6, 4 sec, 0234+285) Please make sure that the autoftp is set up correctly. Good luck with the session! Yurii Schedule for JODRELL1 (Code Jb ) Page 2 Ftp test UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up. Early: Seconds between end of slew and start. Dwell: On source seconds. Disk: GBytes recorded to this point. TPStart: Recording start time. Frequencies are LO sum (band edge).

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 64.7 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.
