CRF-S12 (Southern Hemisphere Astrometry) 2008 September 13 (DOY 257) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crfs12.skd Nominal Start: 20:20 U.T. on 2008 September 13 (DOY 257) first observation at 20:20 U.T. on 2353-686 Hh-Ho-Ti Nominal Stop: 20:20 U.T. on 2008 September 14 (DOY 258) last observation at 20:16 U.T. on 0155-549 Hh-Ho-Ti Correlator: WACO at Washington, DC Station Codes # of tapes # of scans Occupation Code HARTRAO J 1.5 209 HOBART26 H 1.5 209 TIDBIN64 T 1.5 207 Total number of observations (delay measurements): 623 Total number of scans in the schedule: 209 Purpose ======= Astrometric observations to strenghten the ICRF in the Southern Hemisphere. Schedule ======== This is a new schedule generated by Alan Fey using sked. There are 25 new (never observed) sources. 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) = 11.2 Min = 4.0 Max = 23.2 (Baseline Hh-Ti on 0155-549) RMS = 4.5 Total time: 1441 minutes ( 24.0 hours).
