CRF-11 (Celestial Reference Frame) 2001 May 15 Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crf11.skd Nominal Start: 20:00 U.T. on June 6 (day 157) first observation at 20:00 U.T. on 2145+067 for Ho-Kk-Ts Duration: 24 hours Nominal Stop: 20:00 U.T. on June 7 (day 158) last observation at 19:57 U.T. on 2211-388 for Ho-Kk-Ts Correlator: WACO at Washington, DC Station Codes # of tapes # of obs Occupation Code HOBART26 H Ho 2.4 422 KOKEE K Kk 0.7 414 TSUKUB32 T Ts 0.5 394 Total number of observations (delay measurements): 615 Total number of scans in the schedule: 299 Purpose ======= Astrometric observations to strenghten the ICRF by observing ICRF Candidate sources and less well observed ICRF Defining sources. 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. SKED Summary from file ./crf11.skd for experiment CRF-11 (all scans with at least one subnet station) Average number of obs. per baseline per source (normalized by up-time) = 6.7 Min = .0 Max = 17.5 (Baseline Kk-Ts on 0552+398) RMS = 4.6 Total time: 1441 minutes ( 24.0 hours).
