Thanks. Please send the disk pack by express to JIVE COVER LETTER: NOTE: This is version 2 of N09Q2! This is the schedule for the Q-band NME of session 3/2009, to be observed on 12 November 2009, 02:00 - 07:000 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). Phase-referencing will NOT be tested, because the switching time would be prohibitively small (VLBA Scientific Memorandum 24). Please make sure that the autoftp is set up correctly. Good luck for the session! Stefanie Schedule for EB_VLBA (Code Eb ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask. blank => Up.
