CRDS-23 (Southern Hemisphere Astrometry) 2005 September 5 (DOY 248) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds23.skd Nominal Start: 12:00 U.T. on 2005 September 5 (DOY 248) first observation at 12:00 U.T. on 1718-649 Hh-Ho Duration: 24 hours Nominal Stop: 12:00 U.T. on 2005 September 6 (DOY 249) last observation at 11:59 U.T. on 1657-562 Hh-Ho Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HARTRAO J 1.5 184 HOBART26 H 1.5 184 Total number of observations (delay measurements): 184 Total number of scans in the schedule: 184 Purpose ======= Astrometric observations to strenghten the ICRF in the Southern Hemisphere. Schedule ======== This is a new schedule generated by Alan Fey using sked. Correlation =========== This experiment will be correlated at the WACO Correlator. Tapes should be shipped to Washington, DC as soon after the experiment as practical. Special procedures ================== Note: this experiment uses the 128 Mb/s Mk4 mode 128-16-1 (GEOSX2F). Summary ======= The following listing is a summary of the observations in this schedule. Average number of obs. per baseline per source (normalized by up-time) = 12.2 Min = 10.2 Max = 15.7 (Baseline Hh-Ho on 1004-500) RMS = 1.8 Total time: 1441 minutes ( 24.0 hours).
