Session Notes for R1 (Rapid Turnaround Monday) session: r1202 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 R1202 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see master schedule Nominal start: 2005-346-17:00:00 Nominal end: 2005-347-17:00:00 Current yyyyddd: 2005346 (2005.95) ( 13717 MJD, MON. 12DEC.) Greenwich sidereal time: 22:25:58.00 (17: 0: 0 UT) Sun's RA and DEC: 17h 19.8m -23d 7.0 =========================================================== 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 0454-234 05346-170000| 65 65 | 1611+343 05346-170000| 40 58 59 59| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Gc Hh Ma Sh Tc Wz 1954-388 05347-164537| 48 48 | 0528+134 05347-164723| 40 40 40 40| 0014+813 05347-164949| 65 65| 3C418 05347-165317| 48 65 65| =========================================================== SKED Summary from file ./r1202.skd for experiment R1202 (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 Gc-Tc on 1334-127) RMS = 9.8 Total time: 1434 minutes ( 23.9 hours).
