COVER INFORMATION Station: WSTRBORK (Code Wb ) Experiment: Network Monitoring Experiment Exp. Code: N11L4 Schedule Version: 1.00 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: Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the 18cm NME on 31 October 2011 involving 12 antennas: Ef Wb Jb1 On Mc Tr Sv Zc Bd Ur Sh Hh The NME uses a standard setup with 512 Mbps, otherwise it is somewhat unusual. In addition to the usual ftp fringe finding, the main purpose of this NME is to collect test data to use with the primary beam correction model of the future multi-phase-center experiments, including EP077 and EG057 in the L-band segment of this session. Unfortunately no standard EVN fringe-finder is visible to all antennas for this time interval. Thus we use two strong compact sources from the RRFID VLBA database: J1925+2106 (in Sep 2008 S-band flux ~1.4 Jy, X-band flux ~0.9 Jy) J2023+3153 (in Jan 2009 S-band flux ~0.9 Jy, X-band flux ~0.4 Jy) Since Ef has the smallest beam size in the EVN (FWHM ~ 6 arcmin at 18 cm), it was chosen as the offset unit. Test pointings are done to a number of positions offset from J1925+2106: OFF+0.5D -- 0.5 Ef beam (1.5 arcmin) in positive Dec direction OFF+1.5D -- 1.5 Ef beam (4.5 arcmin) in positive Dec direction OFF+2.0D -- 2.0 Ef beam (6.0 arcmin) in positive Dec direction OFF+4.0D -- 4.0 Ef beam (12 arcmin) in positive Dec direction FWHM positions are sampled in a cross pattern OFF+1.0R -- 1.0 Ef beam radius (3 arcmin) in positive RA direction OFF-1.0R -- 1.0 Ef beam radius (3 arcmin) in negative RA direction OFF+1.0D -- 1.0 Ef beam radius (3 arcmin) in positive Dec direction OFF-1.0D -- 1.0 Ef beam radius (3 arcmin) in negative Dec direction J2023+3153 is used only for the ftp testing (if J1925+2106 is unsuitable for some reason). There is no phase referencing section in this experiment. Four ftp tests are scheduled: ~12:23:10 UT (scan 5, 4 sec, J1925+2106) ~13:26:20 UT (scan 21, 8 sec, J1925+2106) ~14:09:30 UT (scan 31, 8 sec, J2023+3153) ~14:56:00 UT (scan 42, 4 sec, J2023+3153) Two 8 sec ftp samples are chosen for the (hopefully improbable) case of both sources turning out to be unusually weak. Please make sure that the autoftp is set up correctly. Good luck with the session! And happy Halloween :) Yurii Schedule for WSTRBORK (Code Wb ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.
