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 strong calibrators: 0234+285, 3C84 for ftp-fringe tests; Ftp-fringe tests are scheduled every half hour throughout the experiment: 08:25:00 (scan 2, 2 sec, 0234+285) 08:55:00 (scan 4, 2 sec, 0234+285) 09:25:00 (scan 6, 2 sec, 0234+285) 09:55:00 (scan 8, 2 sec, 0234+285) 10:25:00 (scan 10, 2 sec, 0234+285) 10:55:00 (scan 12, 2 sec, 3C84) 11:25:00 (scan 14, 2 sec, 3C84) 11:55:00 (scan 16, 2 sec, 3C84) All the best to everyone involved Katharina Schedule for HART (Code Hh ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.
