COVER INFORMATION Station: SHANGHAI (Code Sh ) Experiment: Observations of the field around NGC3516 Exp. Code: ef008 Schedule Version: 1.00 Processed by SCHED version: Release of 12 Jan. 2001 PI: Tony Foley Address: NFRA Postbus 2, 7990 AA Dwingeloo The Netherlands Phone: +31 521 595100 EMAIL: foley@nfra.nl Fax: +31 521 597332 Phone during observation: +31 593 598 719 Observing mode: continuum Notes: Several sources in a field of about 1deg COVER LETTER: This is a plain continuum observation of a number of sources around (and including) NGC3516. The idea is to check for relative movements, so the longer baselines (mostly including Torun, Urumqi and Shanghai) are VITALLY IMPORTANT. If you see any problems with this let me know as soon as possible Good observing to you all, and thanks in advance.
