! Start file bw090n.key ! First of the four extension sessions of BW090 ! 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 ! This file has geodetic blocks added. It is based on the original ! BW090J. ! ================================================================= ! General description of the observations - Cover Letter ! ================================================================= coverlet / This is part of a 4 session to a 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 for the original 10 sessions. The extension was requested after experiencing lots of failures in the first 7 epochs. 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 / ! ! ================================================================ !
