SUMMARY FILE FOR PROJECT: BJ046A COVER INFORMATION: Experiment: M87 multi-epoch at 90cm Exp. Code: BJ046A Start Day 3 is Sat 3 Jan 2004 MJD 53007 Schedule Version: 1.00 Processed by SCHED version: Release of 18 Sept. 2003 PI: Bill Junor Address: ISR-1, Space & Atmospheric Sciences MS D466, LANL, P.O.

Phone: 505 667 0788 EMAIL: bjunor@lanl.gov Fax: 505 665 7395 Phone during observation: 505 699 7692 Observing mode: 90cm 128-4-2 Notes: COVER LETTER: BJ046 SUMMARY: 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. The other sessions can involve as little as 2 hours and as few as 6 antennas. The sessions can be run as filler in gaps between other projects. This project can be run prior to Feb 1, 2004, to accumulate test data on baselines to MK. These test observations need not be long --- 2--4 hours but should include 3C147, 1148-001 and 3C274. Tropospheric weather is not a problem. The ionosphere will have a bigger impact. 3C274 is mostly a night-time object now. -------------------------------------------------------------------- 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]: No earlier than Jan 15, 2004. Excluded dates plus reason [none]: 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): 1.050 sec.

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) 3C147 149.7 1148-001 104.2 3C274 99.9 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. For common VLBI bands, this is: 327 MHz 117. deg 610 MHz 81. deg 1.6 GHz 45. deg 2.3 GHz 36. deg 5.0 GHz 23. deg 8.4 GHz 17. deg 15.0 GHz 12. deg 22.0 GHz 9. deg 43.0 GHz 6. deg Source separations in degrees for pairs closer than 15.00 degrees.
