CRDS-19 (Southern Hemisphere Astrometry) 2005 May 10 (DOY 130) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds19.skd Nominal Start: 22:30 U.T. on 2005 May 10 (DOY 130) first observation at 22:30 U.T. on 1610-771 45-Hh-Sy Duration: 24 hours Nominal Stop: 22:30 U.T. on 2005 May 11 (DOY 131) last observation at 21:26 U.T. on 1511-476 45 last observation at 22:27 U.T. on 1213-172 Hh-Sy Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code DSS45 T 0.3 112 HARTRAO J 1.0 106 SYOWA 1.1 147 Total number of observations (delay measurements): 286 Total number of scans in the schedule: 148 Purpose ======= Astrometric observations to strengthen 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 ================== 45 scheduled for 23hr. Hh and Sy are scheduled for 24hr so they may continue for an additional one hour if so desired. 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) = 7.3 Min = .0 Max = 17.7 (Baseline 45-Hh on 1504-166) RMS = 3.0 Total time: 1440 minutes ( 24.0 hours).
