Session Notes for R1 (Rapid Turnaround Monday) session: r1261 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 R1261 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2007-029-17:00:00 Nominal end: 2007-030-17:00:00 Current yyyyddd: 2007029 (2007.08) ( 14130 MJD, MON. 29JAN.) Greenwich sidereal time: 1:34:15.00 (17: 0: 0 UT) Sun's RA and DEC: 20h 47.4m -17d 53.9 =========================================================== Important Station Information This session has mixed bandwidths since Fortaleza is included. Fortaleza is using 4 MHz. 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 Wettzell from 18:15 U.T. to 19:45 U.T. Wettzell will participate in the intensive session during this period. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ft Hh Ho Ny Sh Tc Wf Wz 1124-186 07029-170000| 40 40 | 3C446 07029-170000| 152 88 152 125 115| OJ287 07029-170314| 40 40 40 40| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Hh Ho Ny Sh Tc Wf Wz 0133+476 07030-165502| 200 150 200 177 76| 0637-752 07030-165602| 127 140 140 | =========================================================== SKED Summary from file ./r1261.skd for experiment R1261 (all scans with at least one subnet station) Average number of obs. per baseline per source (normalized by up-time) = 7.1 Min = .0 Max = 90.0 (Baseline Ny-Wz on 1741-038) RMS = 10.5 Total time: 1438 minutes ( 24.0 hours).
