COVER LETTER: BH126 SUMMARY (as of Dec 6, 2004): We request within 1 week to 10 days coordination with planned Chandra X-ray Observatory observations at 4 epochs: 1. 2Jan05 (VLBA 90cm, 90/50cm, L band for 8 hrs/run = BH126 A, B, C). Coordinated also with VLA observation AH862 on 31Dec04. 2. 20Apr05 or later (VLBA 90cm, 90/50cm, L band for 8 hrs/run = BH126 D, E, F). Coordinated also with VLA observation AH862. 3. 1Jun05 (VLBA L-band for 8 hrs = BH126 G). 4. 6Aug05 (VLBA L band for 8 hrs = BH126 H). -------------------------------------------------------------------- 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 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]: Within 1 week to 10 days of 2Jan05 (Chandra Obs) and 31Dec04 (VLA Obs) 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.]: BEGIN = PROJECT_INFO PROJECT_CODE = BH126A TITLE = Monitoring Knot HST-1 in M87 Jet PI_NAME = D.E.
