Session Notes for R1 (Rapid Turnaround Monday) session: r1270 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 R1270 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2007-092-17:00:00 Nominal end: 2007-093-17:00:00 Current yyyyddd: 2007092 (2007.25) ( 14193 MJD, MON. 2APR.) Greenwich sidereal time: 5:42:38.00 (17: 0: 0 UT) Sun's RA and DEC: 0h 46.3m 4d 58.1 =========================================================== 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 1803+784 07092-170000| 40 40 40 106 40 106 40| 2243-123 07092-170251| 40 40 | 4C39.25 07092-170317| 40 40 40 40 40 40| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Hh Kk Ny On Sh Ts Wf Wz 0805+410 07093-165428| 200 200 118 200 200| 1749+096 07093-165454| 40 40 | 1308+326 07093-165714| 40 40 | 1351-018 07093-165845| 52 52 40 | 0727-115 07093-165902| 40 40 40| =========================================================== SKED Summary from file ./r1270.skd for experiment R1270 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 9.5 Min = .0 Max = 90.0 (Baseline Hh-Ny on 1741-038) RMS = 10.0 Total time: 1440 minutes ( 24.0 hours).
