Session Notes for R1 (Rapid Turnaround Monday) session: r1255 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2006.html#r1 for the session purpose. =========================================================== Parameter values for experiment R1255 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2006-352-17:00:00 Nominal end: 2006-353-17:00:00 Current yyyyddd: 2006352 (2006.96) ( 14088 MJD, MON. 18DEC.) Greenwich sidereal time: 22:48:40.00 (17: 0: 0 UT) Sun's RA and DEC: 17h 45.3m -23d 23.7 =========================================================== Important Station Information Ny Alesund and Zelenchukskaya were tagged along to this session. Westford was also tagged along to this session because Westford has been down for two weeks with a servo failure. There is a 75% chance that Westford will be ready to observe on Monday, December 18. =========================================================== 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 Hh Ny On Tc Ts Wf Wz Zc 0235+164 06352-170433| 41 40 41 40 40 40| 1611+343 06352-170707| 80 188 188 91 90 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Hh Ny On Tc Ts Wf Wz Zc 0602+673 06353-165014| 75 113 113 113 61 | 0208-512 06353-165022| 100 100 | 1124-186 06353-165327| 116 116 | CTA26 06353-165516| 53 53 40 40| 0458-020 06353-165800| 94 59 94 40| =========================================================== SKED Summary from file ./r1255.skd for experiment R1255 (all scans with at least one subnet station) Average number of obs. per baseline per source (normalized by up-time) = 9.7 Min = .0 Max = 144.0 (Baseline Tc-Ts on 0552+398) RMS = 13.8 Total time: 1440 minutes ( 24.0 hours).
