EUROPE-87 (EUROPEAN Geodetic VLBI Network session No. 87) 2007 May 22/23 doy 142-143 Institute for Geodesy and GeoInformation of the University of Bonn, Germany Nominal start time: 2007-142-1730 UT Nominal end time: 2007-143-1730 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. ATTENTION to all participate network stations ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! We have a new and different frequence setup for all stations! Please be carefully and setup the recording mode as discribed in the schedule and as well as in this Experiment INFO file. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! STATION INFO ============ DSS65 and Eb cannot participate in this experiemnt. Fotunately Mc are willing to observe !
