EUROPE-145 (EUROPEAN Geodetic VLBI Network session No.145) 2017 May.03-04 doy 123-124 Institute for Geodesy and GeoInformation of the University of Bonn, Germany Nominal start time: 2017-123-1830 UT Nominal end time: 2017-124-1830 UT Duration: 24 hrs Correlator: BONN PARTICIPATING STATIONS (10) ====================== Bd=BADARY Sm=CRIMEA 6a=DSS65A Nt=NOTO Ny=NYALES20 Sv=SVETLOE Wn=WETTZ13N Wz=WETTZELL Ys=YEBES40M Zc=ZELENCHK 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. The sky coverage for all stations were optimized. The minimum SNR on all baselines at X/S-band are set to 25/23. Comment ======= There are no observations for Wettzell from 18:20 U.T. to 19:40 U.T. Wettzell will participate in the intensive session during this 1.5 hour period.
