Session Notes for R1 (Rapid Turnaround Monday) session: r1262 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2007.html#r1 for the session purpose. =========================================================== Parameter values for experiment R1262 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2007-036-17:00:00 Nominal end: 2007-037-17:00:00 Current yyyyddd: 2007036 (2007.10) ( 14137 MJD, MON. 5FEB.) Greenwich sidereal time: 2: 1:51.00 (17: 0: 0 UT) Sun's RA and DEC: 21h 15.9m -15d 53.3 =========================================================== Important Station Information 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. Ny Alesund was tagged along to this session. =========================================================== There are no observations for Kokee and Wettzell from 18:15 U.T. to 19:45 U.T. Kokee and Wettzell will participate in the intensive session during this period. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Hh Kk Ny On Sh Ts Wf Wz 1739+522 07036-170000| 40 40 40 40 40 40 40| 2121+053 07036-170144| 40 40 40| 1111+149 07036-170206| 91 91 | 2255-282 07036-170309| 92 92 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Hh Kk Ny On Sh Ts Wf Wz 0229+131 07037-165819| 89 75 89 84 40| 1611+343 07037-165820| 40 40 40 | =========================================================== SKED Summary from file ./r1262.skd for experiment R1262 (all scans with at least one subnet station) Average number of obs. per baseline per source (normalized by up-time) = 9.9 Min = .0 Max = 96.0 (Baseline Ts-Wf on 0048-097) RMS = 10.4 Total time: 1439 minutes ( 24.0 hours).
