Code: BH135D Schedule Version: 1.00 Processed by SCHED version: 6.02 July 2005 PI: Teddy Cheung Address: KIPAC, Stanford University Varian Physics Bldg, 382 Via Pueblo Mall Stanford CA 94305-4060, USA Phone: 650 723 8025 EMAIL: teddy3c@stanford.edu Fax: 650 725 4096 Phone during observation: 650 723 8025 Observing mode: 18cm 128-8-1 Notes: COVER LETTER: This is BH135D (item 3 below). BH135C and BH135D should be coordinated near VLA run scheduled to be on February 14/15 0800-1600 LST. BH135 SUMMARY: 1. Oct05 (VLBA L band for 8 hrs = BH135 A) 2. Dec05 (VLBA L band for 8 hrs = BH135 B) 3. Feb06 (VLBA L band, and P+50cm for 8 hrs each = BH135 C, D) coordinated with VLA run. 4. May06 (VLBA L band, and P+50cm for 8 hrs each = BH135 E, F) coordinated with VLA run. 5. Jul06 (VLBA L band, and P+50cm for 8 hrs each = BH135 G, H) coordinated with VLA run. -------------------------------------------------------------------- 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 [7]: 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 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]: Near the VLA run on February 14/15, 0800-1600 LST. Excluded dates plus reason [none]: Preferred interval between segments in days [none]: Special conditions (e.g., a series with different spacings in time) [See the comments at the top.]: Schedule for VLBA_PT (Code Pt ) Page 2 Monitoring Knot HST-1 in M87 Jet UP: D => Below limits; H => Below horizon mask. blank => Up.
