From analysts@aoc.nrao.edu Fri Dec 1 08:35:47 2006 Date: Fri, 01 Dec 2006 08:35:00 -0700 From: Data Analysts To: vlbiobs@aoc.nrao.edu Subject: [Fwd: BB234 Schedules] [ Part 2: "Included Message" ] Date: Fri, 1 Dec 2006 12:18:34 +0000 (GMT) From: Edward Boyce To: Data Analysts Subject: BB234 Schedules Dear analysts, please find attached my keyin file for HSA observation BB234 (scheduled for 21/22 December), and a modified VLA observe file to use 20 VLA only minutes at the start. This is a 512 Mb/s observation, and I had to specify the recording setup by hand. Craig Walker said that 8 Mbps / track was necessary for correlation, and to be sure I was recording at this rate (rather than 16 Mbps / track). I think the setup meets this requirement, but please check that I got it right. I included fringe finder scans of J2253+1608 during the short time when both Arecibo and Mauna Kea can see this source, so the only two fringe finder scans are close together (2133 and 2231). Let me know if this it's OK to have just these two scans. I could add fringe finder scans between 2230 and 0445, but these could not include Arecibo. I left numerous 1 minute gaps in the schedule to make sure that non-VLBA antennas are on source when the cal diode fires. However I'm assuming that all stations will use disk, so I did not leave regular 4 minute gaps for tape readback checks (there's one 4 minute gap when Arecibo slews to the fringe finder). If any stations are going to use tape, let me know and I can put in some gaps. - Edward.
