EUROPE-76 (EUROPEAN Geodetic VLBI Network session No. 76) 2005 July 04/05 doy 185/186 Geodetic Institute of the University of Bonn, Germany Nominal start time: 185-12h00 UT Nominal end time: 186-12h00 UT Duration: 24 hrs Purpose ======= The purpose of this experiment is to determine station coordinates and their evolution in the southern part of the European geodetic VLBI network with the highest precision possible. Schedule ======== The schedule was optimized for local sky coverage. Scans are scheduled to have scan length purely according to SNR limits. No time second modulo is applied. The sky coverage for all stations were optimized. The minimum SNR on all baselines is at X band and at S band different.

Greenwich sidereal time: 6:50:23.00 (12: 0: 0 UT) Sun's RA and DEC: 6h 54.8m 22d 50.4 =========================================================== There are no observations for Wettzell from 18:30 U.T. to 19:30 U.T. Wettzell will participate in the intensive session during this one hour period. =========================================================== Noto is scheduled in tagalong mode, due to the fact that they did not know if they can fix their antenna motor problem until this observation time. =========================================================== First observations Observation listing from file euro76.skd for experiment EURO76 Source Start DURATIONS name yyddd-hhmmss Sm 65 Mc Mh Nt Ny On Sv Wz 4C39.25 05185-120000| 40 40 40 49 40 49 40 40| 1611+343 05185-120334| 164 164 64 134 40 86| 1044+719 05185-120833| 360 40 100 360 180 238 360 116 220| =========================================================== Last observations 0955+476 05186-114249| 360 42 106 360 193 254 360 124 235| End of listing. =========================================================== Average number of obs. per baseline per source (normalized by up-time) = 5.9 Min = .0 Max = 135.0 (Baseline Sm-Ny on 1741-038) RMS = 11.2 Total time: 1428 minutes ( 23.8 hours).
