CRF-39 (Southern Hemisphere Astrometry) 2006 April 11 (DOY 101) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crf39.skd Nominal Start: 18:00 U.T. on 2006 April 11 (DOY 101) first observation at 18:00 U.T. on 1016-311 Ft-Hh-Nt Duration: 24 hours Nominal Stop: 18:00 U.T. on 2006 April 12 (DOY 102) last observation at 17:56 U.T. on 0534-340 Ft-Hh-Nt Correlator: WACO at Washington, DC Station Codes # of tapes # of scans Occupation Code FORTLEZA F 5.6 153 HARTRAO J 1.6 176 NOTO S 1.0 149 Total number of observations (delay measurements): 428 Total number of scans in the schedule: 176 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 Mk4 mode 128-16-1NB. 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) = 13.2 Min = 3.3 Max = 23.8 (Baseline Ft-Hh on 1243-072) RMS = 3.9 Total time: 1444 minutes ( 24.1 hours).
