COVER INFORMATION Station: JODRELL1 (Code Jb ) Experiment: Network Monitoring Experiment Exp. Code: N12L1 Schedule Version: 2.00 Processed by SCHED version: 9.40 Release Jan. 13, 2011. PI: Yurii Pidopryhora Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596548 EMAIL: pidopryhora@jive.nl Fax: Phone during observation: +31-521-596548 Observing mode: Notes: Cheers Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the 18cm NME on 05 March 2011 involving 12 antennas: Eb Wb Jb1 On Mc Tr Sv Zc Bd Ur Sh Hh In this session the main L-band ftp test is separate from the NME (F12L1), but in addition we schedule a couple of the ftp-tests here, just in case some additional checking is needed. The NME uses a standard setup and consists of long integrations on strong sources and a phase-referencing part, 0657+172 is a Jy-class source from VLBA RRFID database (1.23 Jy in S-band as of Oct 2009). It is definitely well resolved, so it could be weak for the long baselines. DA193 and 4C39.25 are standard fringe-finders. The phase-referencing part uses J0954+2639, a 100 mJy-class calibrator as a target and J0956+2515 as a phase-referencing source. J0956+2515 was successfully used as an ftp-fringe finder in N11C2. Its flux based on the pipelined data was ~0.45 Jy for June 2011. It is almost point-like. Two ftp tests are scheduled: ~16:14 UT (scan 2, 4 sec, 0657+172) ~17:18 UT (scan 8, 4 sec, DA193) Please make sure that the autoftp is set up correctly. Good luck with the session!
