CRF-DS5 (Southern Hemisphere Astrometry) 2003 May 20 (DOY 140) Notes prepared by Alan Fey, U.S. Naval Observatory Schedule name: crfds5.skd Nominal Start: 17:30 U.T. on 2003 May 20 (DOY 140) first observation at 17:30 U.T. on 1505-496 Hh-Ho-Pa Duration: 24 hours Nominal Stop: 17:30 U.T. on 2003 May 21 (DOY 141) last observation at 16:59 U.T. on 1511-476 Hh last observation at 17:31 U.T. on 1657-562 Ho-Pa Correlator: WACO at Washington, DC Station Codes # of tapes # of scans Occupation Code HARTRAO J 0.6 189 HOBART26 H 2.1 234 PARKES64 P 2.5 224 Total number of observations (delay measurements): 583 Total number of scans in the schedule: 237 Purpose ======= Astrometric observations to strenghten the ICRF in the Southern Hemisphere. There are 29 new sources; the remainder are ICRF Defining or Candidate 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. Average number of obs. per baseline per source (normalized by up-time) = 7.8 Min = 2.0 Max = 20.5 (Baseline Hh-Ho on 0107-610) RMS = 3.0 Total time: 1442 minutes ( 24.0 hours).
