EUROPE-78 (EUROPEAN Geodetic VLBI Network session No. 76) 2005 Dec 13/14 doy 347-348 Geodetic Institute of the University of Bonn, Germany Nominal start time: 347-17h30 UT Nominal end time: 348-17h30 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. REMARK ====== Crimea is scheduled in tag along mode,because of not yet solved LO problems.
