EURR&D-02 (EUROPEAN Geodetic VLBI Network session No.02 ) 2017 Sept.13/14 doy 256-257 Institute for Geodesy and GeoInformation of the University of Bonn, Germany Nominal start time: 2017-256-1800 UT Nominal end time: 2017-257-1800 UT Duration: 24 hrs Correlator: BONN PARTICIPATING STATIONS (8 ) ====================== Ma=MATERA Mc=MEDICINA Mh=METSAHOV Ny=NYALES20 On=ONSALA60 Wn=WETTZ13N Wz=WETTZELL Ys=YEBES40M 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. The sky coverage for all stations were optimized. The minimum SNR on all baselines at X/S-band are set to 24/22. Comment ======= A new freq setup mode are used in this EURR&D. Beginning with 2017 we will observe alternating in different frequency setups. The named EURR&D-xx will observe with 512Mbps and wide band (CONT11 setup).
