CRDS-70 (Southern Hemisphere Astrometry) 2014 April 7 (DOY 097) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds70.skd Nominal Start: 07:00 U.T. on 2014 April 7 (DOY 097) first observation at 07:00 U.T. on 2355-534 Hh-Hb-Ho-Ke-Ww-Yg Duration: 24 hours Nominal Stop: 07:00 U.T. on 2014 April 8 (DOY 098) last observation at 06:54 U.T. on 0002-478 Hh-Hb-Ho-Ke-Ww-Yg Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HARTRAO J 146 HOBART12 146 HOBART26 142 KATH12M 112 WARK12M 122 YARRA12M 140 Total number of observations (delay measurements): 1884 Total number of scans in the schedule: 146 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) = 6.7 Min = 1.4 Max = 27.5 (Baseline Hh-Ke on 1144-379) RMS = 4.2 Total time: 1441 minutes ( 24.0 hours).
