COVER INFORMATION Station: JODRELL2 (Code Jb ) Experiment: Network Monitoring Experiment Exp. Code: N12M1 Schedule Version: 1.00 Processed by SCHED version: 9.40 Release Jan. 13, 2011. PI: Gabriele Surcis Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596508 EMAIL: surcis@jive.nl Fax: Phone during observation: +31-521-596508 Observing mode: Notes: 5cm NME and ftp fringe test for session 3/2011 (512 Mbps, L+R, 2-bit sampling, 8 MHz filters) Please send the disk pack by express to JIVE Please DO NOT use the phase cal signal. COVER LETTER: This is the schedule for the 5cm NME and ftp fringe-test on 23 February 2012 involving 8 antennas: Eb Wb1 JB2 On25 Mc Tr Ys. The NME uses a setup typical for methanol spectral line experiments, but with 16 channels, i.e. using both sidebands of all BBCs, and 8 MHz filters. The schedule consists of long integrations on strong calibrators like J2052+3635 and 0234+285 as well as phase-referencing parts with a methanol maser and a continuum source as targets, respectively. Four ftp-fringe tests are scheduled throughout the experiment: ~12:06 (scan 2, 4 sec, 0234+285) ~12:52 (scan 14, 4 sec, 0234+285) ~13:32 (scan 27, 4 sec, 0234+285) ~14:50 (scan 46, 4 sec, 0234+285) Please make sure that the autoftp is set up correctly. Thanks! Since this schedule includes a spectral line source (W75N), please switch OFF the phase cal signal! !!! PCAL is OFF for this experiment !!! Good luck with the session!

SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) W75N 57.9 0234+285 72.4 J0258+2900 76.8 J2052+3635 51.3 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz. For common VLBI bands, this is: 327 MHz 117. deg 610 MHz 81. deg 1.6 GHz 45. deg 2.3 GHz 36. deg 5.0 GHz 23. deg 8.4 GHz 17. deg 15.0 GHz 12. deg 22.0 GHz 9. deg 43.0 GHz 6. deg
