CRDS-15 (Southern Hemisphere Astrometry) 2004 December 20 (DOY 355) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds15.skd Nominal Start: 12:00 U.T. on 2004 December 20 (DOY 355) first observation at 12:00 U.T. on 1935-692 Ho-Hh Duration: 24 hours Nominal Stop: 12:00 U.T. on 2004 December 21 (DOY 356) last observation at 11:57 U.T. on 0131-522 Ho-Hh Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HARTRAO J 1.6 185 HOBART26 H 1.6 185 Total number of observations (delay measurements): 185 Total number of scans in the schedule: 185 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 ================== Note: this experiment uses the 128 Mb/s Mk4 mode 128-16-1 (GEOSX2F). 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) = 12.0 Min = 8.2 Max = 18.9 (Baseline Hh-Ho on 2106-413) RMS = 2.1 Total time: 1441 minutes ( 24.0 hours).
