CRF-90 (Southern Hemisphere Astrometry) 2015 September 29 (DOY 272) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crf90.skd Nominal Start: 17:30 U.T. on 2015 September 29 (DOY 272) first observation at 17:30 U.T. on 2355-106 Ft-Hh-Nt-T6 Duration: 24 hours Nominal Stop: 17:30 U.T. on 2015 September 30 (DOY 273) last observation at 17:29 U.T. on 1954-388 Ft-Hh-Nt-T6 Correlator: Station Codes # of tapes # of scans Occupation Code FORTLEZA 101 HARTRAO J 169 NOTO 169 TIANMA65 80 Total number of observations (delay measurements): 543 Total number of scans in the schedule: 169 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) = 11.7 Min = 0.0 Max = 96.0 (Baseline Ft-T6 on 1406-076) RMS = 10.1 Total time: 1446 minutes ( 24.1 hours).
