EUROPE-94 (EUROPEAN Geodetic VLBI Network session No. 94) 2008 July 08/09 doy 190-191 Institute for Geodesy and GeoInformation of the University of Bonn, Germany Nominal start time: 2008-190-1730 UT Nominal end time: 2008-191-1730 UT Duration: 24 hrs ----------------------------------------------------------------- Note: This is an updated schedule with the following changes: - reduced elevation slew rate for Eb (10 deg/min) - Bd and Ys both removed from schedule (as they are not available on doy 190/191) Changes made: July 2, 2008 (dbb) ----------------------------------------------------------------- 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. e-VLBI Transfer =============== We will try to transfer data via eVLBI from Mh, On and Wz !
