CRDS-67 (Southern Hemisphere Astrometry) 2013 September 02 (DOY 245) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds67.skd Nominal Start: 16:30 U.T. on 2013 September 02 (DOY 245) first observation at 16:30 U.T. on 2244-372 Hh-Hb-Ho-Ke-Ww-Yg Duration: 24 hours Nominal Stop: 16:30 U.T. on 2013 September 03 (DOY 246) last observation at 16:24 U.T. on 2232-488 Hh-Hb-Ho-Ke-Ww-Yg Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HARTRAO J 149 HOBART12 148 HOBART26 149 KATH12M 122 WARK12M 124 YARRA12M 148 Total number of observations (delay measurements): 1978 Total number of scans in the schedule: 149 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) = 7.4 Min = 1.6 Max = 24.8 (Baseline Hh-Ho on 0534-340) RMS = 4.5 Total time: 1446 minutes ( 24.1 hours).
