EUROPE-137 (EUROPEAN Geodetic VLBI Network session No.137) 2015 Sept. 07-08 doy 250-251 Institute for Geodesy and GeoInformation of the University of Bonn, Germany Nominal start time: 2015-250-1200 UT Nominal end time: 2015-251-1200 UT Duration: 24 hrs Correlator: BONN PARTICIPATING STATIONS ====================== 6a=DSS65A Mh=METSAHOV Nt=NOTO Ny=NYALES20 On=ONSALA60 Sm=CRIMEA Wz=WETTZELL (Wn=WETTZ13N) 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 is at X band and at S band set to 25. Comment ======= Wn (TWIN Wettzell North) was scheduled in tag-along mode.
