Session Notes for R1 (Rapid Turnaround Monday) session: r1269 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 R1269 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2007-085-17:00:00 Nominal end: 2007-086-17:00:00 Current yyyyddd: 2007085 (2007.23) ( 14186 MJD, MON. 26MAR.) Greenwich sidereal time: 5:15: 2.00 (17: 0: 0 UT) Sun's RA and DEC: 0h 20.8m 2d 14.8 =========================================================== Important Station Information Ny Alesund was tagged along to this session. 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. =========================================================== 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 Sh Ts Wf Wz 3C418 07085-170000| 40 60 70 40 70 65| 2121+053 07085-170155| 121 121 | 4C39.25 07085-170307| 40 40 40 40 40| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Hh Kk Ny Sh Ts Wf Wz 0229+131 07086-165718| 104 40 104 | OJ287 07086-165730| 40 40 40| 1308+326 07086-165859| 40 40 | =========================================================== SKED Summary from file ./r1269.skd for experiment R1269 (all scans with at least one subnet station) Average number of obs. per baseline per source (normalized by up-time) = 11.0 Min = .0 Max = 60.0 (Baseline Kk-Wz on 1749+096) RMS = 10.3 Total time: 1440 minutes ( 24.0 hours).
