Code: BG155 Schedule Version: 4.00 Processed by SCHED version: NRAO internal release of 4 October 2004 PI: Lincoln J. Greenhill Address: Harvard-Smithsonian CfA, MS 42 60 Garden St Cambridge, MA 02138 USA Phone: 617 495 7194 EMAIL: lincoln@cfa.harvard.edu Fax: 617 495 7345 Phone during observation: 617 851 8918 Observing mode: 512-8-2 1.3 cm Notes: VLA: toss out antennas without good positions. VLA: toss out outer 1-2 antennas on each arm for phasing,if nec. VLA: BBC 1/8 lie outside the VLA 50 MHz IF. This is OK. VLA (5m) & GBT (10m) pointing every roughly 1 - 1.3 hours.
