CRF-93 (Southern Hemisphere Astrometry) 2016 February 24 (DOY 055) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crf93.skd Nominal Start: 18:00 U.T. on 2016 February 24 (DOY 055) first observation at 18:00 U.T. on 1349-439 Hb-Ho-Kb-Ke-Kk-Km-Yg Duration: 24 hours Nominal Stop: 18:00 U.T. on 2016 February 25 (DOY 056) last observation at 17:55 U.T. on 1443-162 Hb-Ho-Kb-Ke-Kk-Km-Yg Correlator: Station Codes # of tapes # of scans Occupation Code HOBART12 184 HOBART26 183 KASHIM34 163 KATH12M 183 KOKEE 174 KUNMING 104 YARRA12M 165 Total number of observations (delay measurements): 3014 Total number of scans in the schedule: 193 Purpose ======= Astrometric observations to strenghten the ICRF in the Southern Hemisphere. Schedule ======== This is a new schedule generated by Alan Fey using sked. Correlation =========== Media should be shipped to the correlator 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) = 10.0 Min = 0.0 Max = 57.6 (Baseline Kk-Km on 1349-439) RMS = 4.7 Total time: 1441 minutes ( 24.0 hours).
