Session Notes for R1 (Rapid Turnaround Monday) session: r1274 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 R1274 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2007-122-17:00:00 Nominal end: 2007-123-17:00:00 Current yyyyddd: 2007122 (2007.33) ( 14223 MJD, WED. 2MAY.) Greenwich sidereal time: 7:40:55.00 (17: 0: 0 UT) Sun's RA and DEC: 2h 37.9m 15d 24.6 =========================================================== Important Station Information This session has mixed bandwidths since Fortaleza is included. Fortaleza is using 4 MHz. Fortaleza has been observing with a warm receiver. The SEFDs for Fortaleza were changed from 3000 for both X and S band to 10000 and 5000 for X-band and S-band, respectively. Ny Alesund and Zelenchukskaya were 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 Ny On Tc Wz Zc 0727-115 07122-170000| 111 40 132 132 52 40| 4C39.25 07122-170358| 40 40 40 40 40 40| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Hh Ny On Tc Wz Zc 0727-115 07123-165326| 111 111 | 1308+326 07123-165354| 40 40 40 | 3C274 07123-165520| 40 40 40 40| 1156+295 07123-165645| 193 140 193 71 | =========================================================== SKED Summary from file ./r1274.skd for experiment R1274 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 7.5 Min = .0 Max = 64.2 (Baseline Ny-On on CTA26 ) RMS = 10.3 Total time: 1440 minutes ( 24.0 hours).
