Code: N09K1 Schedule Version: 1.00 Processed by SCHED version: 8.00 2008 December Release 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 K-band NME and ftp fringe-test on 3 March 2009. The NME uses a setup similar to the following user experiment EM059D and consists of long integrations on strong calibrators like 3C84 and 3C454.3 as well as several ftp-fringe tests and a test of fast phase-referencing. In addition to the ftp fringe-tests on the usual VLBA fringe finders 3C84, 3C454.3 and 4C39.25, tests are scheduled on a source from the RRFID catalog that is strong on long baselines (0202+319) and on the H2O maser source W3OH. Note that the transfer times of Noto and Sheshan (estimates given below) govern the schedule of the ftp-tests. The data transfers are scheduled to begin at ~1215 ( 8 sec, 0202+319, RRFID source) Nt: 30min, Sh: 60min ~1300 ( 8 sec, 3C454.3, fringe finder) Nt: 30min, Sh: --- ~1345 ( 8 sec, W3OH, H2O maser source) Nt: 30min, Sh: 60min ~1430 (16 sec, 3C84, fringe finder) Nt: 60min, Sh: 120min ~1545 (16 sec, 3C454.3, fringe finder) Nt: 60min, Sh: --- ~1700 (16 sec, 4C39.25, fringe finder) Nt: 60min, Sh: 120min Please make sure that the autoftp is set up correctly.
