CRDS-50 (Southern Hemisphere Astrometry) 2011 March 30 (DOY 089) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds50.skd Nominal Start: 18:30 U.T. on 2011 March 30 (DOY 089) first observation at 18:30 U.T. on 1352-632 Hh-Hb Duration: 24 hours Nominal Stop: 18:30 U.T. on 2011 March 31 (DOY 090) last observation at 18:29 U.T. on 1156-663 Hh-Hb Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HARTRAO J 113 HOBART12 113 Total number of observations (delay measurements): 113 Total number of scans in the schedule: 113 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 ================== None 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) = 8.4 Min = 4.1 Max = 14.4 (Baseline Hh-Hb on 0738-674) RMS = 2.9 Total time: 1440 minutes ( 24.0 hours).
