Code: F09Q1 Schedule Version: 1.00 Processed by SCHED version: 8.10 Bug fixs and minor enhancements PI: Stefanie Muehle Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596508 EMAIL: muehle@jive.nl Fax: +31-521-596539 Phone during observation: +31-521-596508 Observing mode: Notes: Please do NOT use the phase cal signal. Thanks. Please send the disk pack by express to JIVE COVER LETTER: This is the schedule for the Q-band ftp fringe-test of session 3/2009, to be observed on 11 November 2009, 12:00 - 14:00 UT. Since many of the usual VLBA fringe finders are rather weak at 7mm, the sources are selected from the latest catalog of CARMA calibrator sources (3mm flux, September 2009). Note that Noto does not have a high-speed connection. Typical transfer times are 25-30 minutes for 245MB (8 sec of data at 256Mbps) and 50-60 minutes for 489MB (16 sec of data at 256Mbps). The ftp-data are scheduled to be transmitted at ~12:10 UT (16 sec of 3C273) ~13:52 UT ( 8 sec of 3C454.3) Please make sure that the autoftp is set up correctly. Good luck for the session!

The solar corona can cause unstable phases for sources too close to the Sun. 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) UHER 41.3 3C273 43.5 3C454.3 119.8 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
