CRF-51 (Southern Hemisphere Astrometry) 2008 April 7 (DOY 098) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crf51.skd Nominal Start: 12:00 U.T. on 2008 April 7 (DOY 098) first observation at 12:00 U.T. on 2325-150 Ft-Hh-Nt Duration: 24 hours Nominal Stop: 12:00 U.T. on 2008 April 8 (DOY 099) last observation at 11:55 U.T. on 0138-097 Ft-Hh-Nt Correlator: WACO at Washington, DC Station Codes # of tapes # of scans Occupation Code FORTLEZA F 6.4 89 HARTRAO J 2.1 89 NOTO S 2.1 89 Total number of observations (delay measurements): 267 Total number of scans in the schedule: 89 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 ================== N/A 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) = 7.7 Min = 2.4 Max = 12.3 (Baseline Ft-Nt on 2306-312) RMS = 1.7 Total time: 1448 minutes ( 24.1 hours).
