COVER INFORMATION Station: HH_DBBC2 (Code Hx ) Experiment: Network Monitoring Experiment Exp. Code: N12L2 Schedule Version: 1.00 Processed by SCHED version: 10.00 Release Sept. 15, 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: Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the 18cm NME on 12 June 2012 involving 13 antennas: Ef Wb Jb1 On Mc Nt Tr Sv Zc Bd Ur Hh Ir and 3 fake DBBC test "stations" HH_DBBC, HH_DBBC2, ON8_DBBC The NME uses a standard setup with 512 Mbps and consists of long integrations on strong sources standard EVN f-finders 0528+134, DA193, 4C39.25 and J1043+2408 (in May 2011 C-band flux ~0.7 Jy based on N11C2 pipeline) Note, that during the observation 0528+134 is only ~10 deg from the Sun. There is no phase referencing section in this experiment. Four ftp tests are scheduled: ~10:08:40 UT (scan 2, 4 sec, 0528+134) ~10:57:50 UT (scan 8, 4 sec, DA193) ~11:45:50 UT (scan 13, 4 sec, 4C39.25) ~12:46:30 UT (scan 20, 4 sec, J1043+2408) Please make sure that the autoftp is set up correctly.
