CRDS-25 (Southern Hemisphere Astrometry) 2006 March 28 (DOY 087) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds25.skd Nominal Start: 17:30 U.T. on 2006 March 28 (DOY 087) first observation at 17:30 U.T. on 1004-500 Hh-Ho Duration: 24 hours Nominal Stop: 17:30 U.T. on 2006 March 29 (DOY 088) last observation at 17:32 U.T. on 0522-611 Hh-Ho Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HARTRAO J 1.8 151 HOBART26 H 1.8 151 Total number of observations (delay measurements): 151 Total number of scans in the schedule: 151 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) = 10.4 Min = 6.7 Max = 18.8 (Baseline Hh-Ho on 1004-500) RMS = 2.2 Total time: 1449 minutes ( 24.1 hours).
