CRDS-48 (Southern Hemisphere Astrometry) 2008 August 27 (DOY 240) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds48.skd Nominal Start: 17:30 U.T. on 2008 August 27 (DOY 240) first observation at 17:30 U.T. on 2300-683 Hh-Ho Duration: 24 hours Nominal Stop: 17:30 U.T. on 2008 August 28 (DOY 241) last observation at 17:27 U.T. on 2109-811 Hh-Ho Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HARTRAO J 1.7 160 HOBART26 H 1.7 160 Total number of observations (delay measurements): 160 Total number of scans in the schedule: 160 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) = 12.4 Min = 8.2 Max = 20.5 (Baseline Hh-Ho on 1116-462) RMS = 3.6 Total time: 1443 minutes ( 24.0 hours).
