From tukasa@oj287.astro.utu.fiFri Jan 17 14:32:29 2003 Date: Fri, 17 Jan 2003 15:27:36 +0200 (EET) From: Tuomas Savolainen To: vlbiobs@cv3.cv.nrao.edu Cc: jromney@cv3.cv.nrao.edu, Kaj Wiik , Esko Valtaoja Subject: BS121A keyin file Dear data analyst, here is our sched keyin file for the dynamically scheduled program BS 121, which is a monitoring program co-ordinated together with observations at the INTEGRAL-satellite. Since the INTEGRAL will observe our target (3C273) on 25th of January, we would like to have our first epoch to be scheduled (weather permitting) as close to that date as possible. Our program consists of altogether five epochs (separated approximately by 60, 60, 60 and 120 days). The observations on all epochs are most likely identical. However, based on the experience from the first epoch, we may want to modify later epochs. Can this be done just by sending a new keyin file? Since we have included 3mm observations to our run, we would like to know a few details concerning 3mm equipment. First, is 3mm already available at Hancock? And secondly, is there a problem, if the command "setup = 3mm" is given to stations which do not posses 3mm receivers? (We would not like to do subarraying unless absolutely necessary.) We decided to make reference pointing to our program source (3C273), since it's flux is currently 22 Jy at 37 GHz (Merja Tornikoski, Mets?hovi monitoring program) and 18 Jy at 86 GHz (end of December, Anne Lahteenmaki, SEST). Any masers giving larger Ta are too far away (> 40 deg) from the program source. We request the reference pointing to be done at 7mm because the acquired Ta is larger and we do not request 3mm weather. Do our scheduling constraints look reasonable? Should we relax them in order to have our observations to be made within a few weeks from the INTEGRAL pointing (25 Jan)? Best regards, Tuomas Savolainen Kaj Wiik --------------
