JB2, WB1, EF, MC, ON85, TR, SV, ZC, BD, HH, SR. The NME uses 16x BBC (8 for each Pol.) of 8MHz bandwidth: Data rate of 512 Mbps. The schedule consists of: - long integrations on a strong calibrator: 3C84 for ftp-fringe tests; Ftp-fringe tests are scheduled every 15 min throughout the experiment: 11:05:00 (scan 2, 2 sec, 3C84) 11:20:00 (scan 4, 2 sec, 3C84) 11:35:00 (scan 6, 2 sec, 3C84) 11:50:00 (scan 8, 2 sec, 3C84) All the best to everyone involved Katharina Schedule for WSTRBORK (Code Wb ) Page 2 FTP Fringe 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) 3C84 23.7 0528+134 18.6 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.
