Session Notes for R1 (Rapid Turnaround Monday) session: r1203 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2005.html#r1 for the session purpose. =========================================================== Parameter values for experiment R1203 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see master schedule Nominal start: 2005-353-17:00:00 Nominal end: 2005-354-17:00:00 Current yyyyddd: 2005353 (2005.97) ( 13724 MJD, MON. 19DEC.) Greenwich sidereal time: 22:53:33.00 (17: 0: 0 UT) Sun's RA and DEC: 17h 50.8m -23d 25.3 =========================================================== 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. =========================================================== 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 Gc Hh Ma Sh Tc Wz 0607-157 05353-170000| 47 47 | 1611+343 05353-170000| 40 58 62 62| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Gc Hh Ma Sh Tc Wz 2243-123 05354-164051| 232 232 | 3C418 05354-164200| 48 66 66| 0955+476 05354-164422| 40 40 40| 0831+557 05354-164545| 40 40| OJ287 05354-164616| 58 58 | 0602+673 05354-164720| 40 40| 0823+033 05354-165006| 210 210 | =========================================================== SKED Summary from file ./r1203.skd for experiment R1203 (all scans with at least one subnet station) Average number of obs. per baseline per source (normalized by up-time) = 6.6 Min = .0 Max = 102.9 (Baseline Hh-Tc on 1611+343) RMS = 9.9 Total time: 1434 minutes ( 23.9 hours).
