JB1, WB1, EF, MC, ON85, T6, UR, TR, Sv, Zc, Bd, Hh, Ir,[Ar], JODRELL2,CAMBG32M,DARNHALL,KNOCKIN,TABLEY. The NME uses 16x BBC (8 for each Pol.) of 8MHz bandwidth: Data rate of 512 Mbps. The schedule consists of: - long integrations on strong calibrators: J1751+0939, J2115+2933 for ftp-fringe tests; Ftp-fringe tests are scheduled every half hour throughout the experiment: 12:24:00 (scan 2, 2 sec, J1751+0939) 12:54:00 (scan 4, 2 sec, J2115+2933) 13:24:00 (scan 6, 2 sec, J2115+2933) 13:54:00 (scan 8, 2 sec, J2115+2933) 14:24:00 (scan 10, 2 sec, J2115+2933) 14:54:00 (scan 12, 2 sec, J2115+2933) All the best to everyone involved Katharina Skype account: jive.support.scientist Schedule for EFLSBERG (Code Ef ) Page 2 Network Monitoring Experiment 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) J1751+0939 57.7 J1848+3219 79.2 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.
