CRF-18 (Southern Hemisphere Astrometry) 2003 May 13 (DOY 133) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crf18.skd Nominal Start: 17:30 U.T. on 2003 May 13 (DOY 133) first observation at 17:30 U.T. on 0727-115 Ft-Hh-Nt Duration: 24 hours Nominal Stop: 17:30 U.T. on 2003 May 13 (DOY 134) last observation at 17:19 U.T. on 0834-201 Ft-Hh-Nt last observation at 17:35 U.T. on 1105-680 Ft-Hh Correlator: WACO at Washington, DC Station Codes # of tapes # of scans Occupation Code FORTLEZA F 3.2 110 HARTRAO J 0.9 127 NOTO S 0.6 98 Total number of observations (delay measurements): 262 Total number of scans in the schedule: 136 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 ================== None. 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) = 4.9 Min = .0 Max = 14.5 (Baseline Hh-Nt on 0722+145) RMS = 3.3 Total time: 1449 minutes ( 24.1 hours).
