EUROPE-77 (EUROPEAN Geodetic VLBI Network session No. 76) 2005 Sep 05/06 doy 248-249 Geodetic Institute of the University of Bonn, Germany Nominal start time: 248-12h00 UT Nominal end time: 249-12h00 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. REMARK ====== Noto is scheduled in tag along mode, due to antenna motor repair. Updated version Sept 2: DSS65 was added to the existing schedule by tagging it along. This was done after updating the horizon mask.
