CRF-31 (Southern Hemisphere Astrometry) 2005 January 25 (DOY 025) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crf31.skd Nominal Start: 17:30 U.T. on 2005 January 25 (DOY 025) first observation at 17:30 U.T. on 0130-171 Ft-Hh-Nt Duration: 24 hours Nominal Stop: 17:30 U.T. on 2005 January 26 (DOY 026) last observation at 17:31 U.T. on 0414-189 Ft-Hh-Nt Correlator: WACO at Washington, DC Station Codes # of tapes # of scans Occupation Code FORTLEZA F 2.8 104 HARTRAO J 1.8 180 NOTO S 1.5 153 Total number of observations (delay measurements): 322 Total number of scans in the schedule: 184 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 Mk3 mode CDPSX-C-4. 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) = 9.8 Min = .0 Max = 25.1 (Baseline Hh-Nt on 1806-458) RMS = 6.5 Total time: 1444 minutes ( 24.1 hours).
