CRDS-28 (Southern Hemisphere Astrometry) 2006 June 26 (DOY 177) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crds28.skd Nominal Start: 17:00 U.T. on 2006 June 26 (DOY 177) first observation at 17:00 U.T. on 1758-651 Hh-Ho Duration: 24 hours Nominal Stop: 17:00 U.T. on 2006 June 27 (DOY 178) last observation at 16:40 U.T. on 1619-680 Hh-Ho Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HARTRAO J 1.8 169 HOBART26 H 1.8 169 Total number of observations (delay measurements): 169 Total number of scans in the schedule: 169 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 schedule is short to facilitate combination of CRDS27 and CRDS28 on two 960 GB MK5 modules. 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) = 11.0 Min = 8.2 Max = 21.8 (Baseline Hh-Ho on 0438-436) RMS = 2.9 Total time: 1428 minutes ( 23.8 hours).
