Session Notes for R1 (Rapid Turnaround Monday) session: r1199 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2005.html#r1 for the session purpose. =========================================================== Important Information about Seshan Since Seshan has only 8 BBCs, there are only 4 being used at X and 4 being used at S. A total of 9 channels are being recorded because one of the X-band converters is used for both upper and lower sideband. =========================================================== Parameter values for experiment R1199 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see master schedule Nominal start: 2005-325-17:00:00 Nominal end: 2005-326-17:00:00 Current yyyyddd: 2005325 (2005.89) ( 13696 MJD, MON. 21NOV.)
