Session Notes for R1 (Rapid Turnaround Monday) session: r1266 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 R1266 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2007-064-17:00:00 Nominal end: 2007-065-17:00:00 Current yyyyddd: 2007064 (2007.18) ( 14165 MJD, MON. 5MAR.) Greenwich sidereal time: 3:52:14.00 (17: 0: 0 UT) Sun's RA and DEC: 23h 3.8m -6d .6 =========================================================== Important Station Information This session has mixed bandwidths since Fortaleza is included. Fortaleza is using 4 MHz. Ny Alesund was tagged along to this session. Hobart was scheduled as a regular station from 17:00 U.T. to 11:30 U.T. Hobart was tagged along to this session from 11:30 U.T. to 17:00 U.T. so that Hobart can participate in a special 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 Ft Ho Kk Ny Tc Ts Wf Wz 1958-179 07064-170000| 200 188 62 200 94 | 3C418 07064-170000| 40 40 40| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Ho Kk Ny Tc Ts Wf Wz 0208-512 07065-165158| 197 197 | 1313-333 07065-165410| 40 40 40 | 1739+522 07065-165628| 40 40 40 40 40| 0602+673 07065-165803| 58 115 115| =========================================================== SKED Summary from file ./r1266.skd for experiment R1266 (all scans with at least one subnet station) Average number of obs. per baseline per source (normalized by up-time) = 8.1 Min = .0 Max = 110.8 (Baseline Tc-Ts on 0537-441) RMS = 11.9 Total time: 1439 minutes ( 24.0 hours).
