CRF-41 (Southern Hemisphere Astrometry) 2006 July 12 (DOY 193) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crf41.skd Nominal Start: 14:00 U.T. on 2006 July 12 (DOY 193) first observation at 14:00 U.T. on 1012-448 Ft-Hh-Nt Duration: 24 hours Nominal Stop: 14:00 U.T. on 2006 July 13 (DOY 194) last observation at 13:59 U.T. on 1213-172 Ft-Hh-Nt Correlator: WACO at Washington, DC Station Codes # of tapes # of scans Occupation Code FORTLEZA F 5.4 149 HARTRAO J 1.5 179 NOTO S 1.1 156 Total number of observations (delay measurements): 431 Total number of scans in the schedule: 179 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) = 13.6 Min = 6.3 Max = 23.2 (Baseline Ft-Hh on 1511-476) RMS = 4.2 Total time: 1441 minutes ( 24.0 hours).
