EUROPE-108 (EUROPEAN Geodetic VLBI Network session No. 108 ) 2010 Nov. 25/26 doy 329-330 Institute for Geodesy and GeoInformation of the University of Bonn, Germany Nominal start time: 2010-329-1200 UT Nominal end time: 2010-330-1200 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. Comment ======= DSS65a can participate only 18 hours, from 329-18:25UT to 330-10:15UT e-VLBI Transfer =============== We will transfer data via eVLBI from Mc and Ny.
