SUMMARY FILE FOR PROJECT: bw067m COVER INFORMATION: Experiment: Image 3C120 at 90cm - calibrator test Exp. Code: bw067m Start Day 346 is Fri 12 Dec 2003 MJD 52985 Schedule Version: 1.00 Processed by SCHED version: Release of 18 Sept. 2003 PI: Craig Walker Address: National Radio Astronomy Observatory P. O. Box O Socorro, New Mexico, 87801 U.S.A. Phone: 505 835 7247 EMAIL: cwalker@nrao.edu Fax: 505 835 7027 Phone during observation: 505 835 7247 Observing mode: 6cm 128-4-2 Notes: COVER LETTER: This project needs about 100 hours times 45 baselines to meet the sensitivity requirements. This time can be accumulated in many separated sessions. One session should be a full track with all antennas to set the calibration and ensure full uv coverage. I have submitted a schedule as bw067c for that session. The other sessions can involve as little as 2 hours and as few as 6 antennas. The observing frequency is 327 MHz. Tropospheric weather is not an issue - any conditions are ok. The ionosphere and the solar corona are potential problems. An outcome of the test observations (bw067a and bw067b) was that we should not observe near the sun. So please don't schedule this in the months of April through July. As per discussions with Dave Medcalf, I have set up this schedule to use a SCHED optimization mode that allows any subset of a full track to be designated by only changing the start time and the overall duration. So, with only modifications to those parameters, this schedule can be used repeatedly to build up the required baseline hours. See the "Initial Scan Information" section in the key file. The schedule uses 1.3 tape passes per hour. Here is the official dynamic scheduling sheet: ================================================================ Preferred Dynamic Contraints. Alter [defaults] as desired. ================================================================ Equipment constraints: Stations. Below each station code, the "o" indicates an [optional] station that is to be used if it is available. Change "o" to "r" if the station is required or change "o" to "n" if the station is not to be used. SC HN NL FD LA PT KP OV BR MK o o o o o o o o o r Minimum number of stations [6]: May we swap PT for a single VLA antenna? [yes] Consult http://www.aoc.nrao.edu/~gtaylor/y1gotcha.html to decide. If you adopt the default, then both PT and VLA1 must be in the stations list in the keyin file. Bands and polarizations. Below each band code, insert "R" if the righthand polarization is to be used, "L" if the lefthand polarization is to be used, "d" if dual polarizations are to be used, or "o" if the band is in your setups but scheduling should not be constrained by its availability. 90cm 50cm 20cm 13cm 6cm 4cm 2cm 1cm 7mm 3mm d Weather constraints: [appropriate for bands marked "L", "R", or "d" above and for at least the minimum number of stations] Date constraints: Preferred date(s), usually a series start [none]: Excluded dates plus reason [none]: April through July (too close to Sun). Preferred interval between segments in days [none]: Special conditions (e.g., a series with different spacings in time) [See the comments at the top.]: CORRELATION REQUESTS (Defaults in parentheses): Correlator (Required if recording): SOCORRO Correlator average time (2 sec): 2.000 sec.

Survey - ICRF Frame - reduced by GSFC group - Aug 2001 The solar corona can cause unstable phases for sources too close to the Sun. SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) J0423-0120 152.4 3C120 159.5 3C147 152.7 3C286 76.0 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz.
