COVER LETTER: This is the schedule for the 3.6 ftp fringe-test on 01 November 2013 involving 12 antennas: Eb Wb On20 Mc Nt Ys Sv Zc Bd Ur Sh Hh (+Md). The schedule consists of long integrations on strong calibrators like 3C286. Two ftp-fringe tests are scheduled throughout the experiment: ~08:15 (scan 2, 2 sec, 3C286) ~08:48 (scan 5, 2 sec, 3C286) Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session! Gabriele Schedule for MC_DBBC (Code Md ) Page 2 X band FTP-FT Experiment 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).
