! Start file bw090a.key ! Schedule for observations for a VLBA movie of M87 at 7mm. ! There will be 10 observations at 5 day intervals, taking about ! two months. The nominal dates should be hit to within a day ! if possible. ! First schedule based on BW088U ! ================================================================= ! General description of the observations - Cover Letter ! ================================================================= coverlet / This 10 session project is designed to provide a fast movie of jet component motions near the black hole in M87. It was proposed after the every-three-week movie made with BW088 was determined to be undersampled. Here is the key information from the time allocation email: PROPOSAL STATUS ( 12/31/2007 ): Approved for dynamic scheduling, high priority CURRENT TIME ALLOCATION: 10 times 10.0 hrs dynamically scheduled centered at LST 12.5 with 256 Mbits/sec recording Note request for 32 output spectral channels per baseband. ------------------------------------------------------------------------- endcover / ! ! ================================================================ ! Preferred Dynamic Constraints. Alter [defaults] as desired. ! ================================================================ ! Requirements the same as BW088, but try to hit target dates within ! one day. ! ! 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 ! r r o o o o o o o r ! Minimum number of stations [9 (6 for 3mm)]: ! May we swap PT for a single VLA antenna? [no] ! VLA would need reference pointing, but can't do with 1 ! antenna. ! 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] ! Emphasize good weather on longest baselines. ! Date constraints: ! Preferred date(s), usually a series start [none]: ! Excluded dates plus reason [none]: ! Preferred interval between segments in days [none]: 21 ! Special conditions (e.g., a series with different ! spacings in time) [none]: ! ! Here are the optimum dates based on the start date of Jan 26, 2008 ! for BW090A. Please try to come as close as possible to each of ! these dates. One day off is ok, 2 tolerable if absolutely necessary, ! but no more. I will give Phillip a version that shows all days and ! known conflicts. ! ! Optimum date DOY Ses.
