CRDS-20 (Southern Hemisphere Astrometry) 2005 June 22 (DOY 173) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds20.skd Nominal Start: 12:00 U.T. on 2005 June 22 (DOY 173) first observation at 12:00 U.T. on 1325-558 Hh-Ho Duration: 24 hours Nominal Stop: 12:00 U.T. on 2005 June 23 (DOY 174) last observation at 11:59 U.T. on 0454-810 Hh-Ho Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HARTRAO J 1.5 176 HOBART26 H 1.5 176 Total number of observations (delay measurements): 176 Total number of scans in the schedule: 176 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) = 11.6 Min = 6.1 Max = 15.7 (Baseline Hh-Ho on 1004-500) RMS = 2.2 Total time: 1440 minutes ( 24.0 hours).
