EUROPE-105 (EUROPEAN Geodetic VLBI Network session No. 105 ) 2010 Mai 19/20 doy 139-140 Institute for Geodesy and GeoInformation of the University of Bonn, Germany Nominal start time: 2010-139-1800 UT Nominal end time: 2010-140-1800 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 ======= Svetloe is scheduled in tag along mode. e-VLBI Transfer =============== We will transfer data via eVLBI from Ny,Mh and Ys(trial) Session Notes for session: eur105 =========================================================== Experiment: EUR105 Description EUROPE-105 Scheduler: IGG/am Correlator: BONN Start: 2010-139-18:00:00 End: 2010-140-18:00:01 Current yyyyddd: 2010139 (2010.38) ( 15336 MJD, WED. 19MAY.)
