EUROPE-70 (EUROPEAN Geodetic VLBI Network session No. 70) Schedule and Notes prepared by Axel Nothnagel, University of Bonn Geodetic Institute Date of experiment: 2003 December 16 Nominal start time: 17h30 UT Nominal end time: 17h30 UT on December 17 Duration: 24 hrs Correlator: Bonn Participating stations: Station Code Effelsberg Eb Matera Ma Medicina Mc Noto Nt NyAlesund Ny Onsala60 On Wettzell Wz Yebes Yb Tape usage and scans to be observed: See summary of schedule below 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 produced by Axel Nothnagel using the automatic mode of sked. The schedule was optimized for local sky coverage. Scans are scheduled to have scan length purely according to SNR limits. No 10-second modulo is applied. The sky coverage for all stations were optimized. Yebes was scheduled in a tagalong mode. However, it still provides 297 scans. The minimum SNR on all baselines is 40 at X band and 25 at S band. SNR of all baselines with Onsala are reduced to 25/20 to avoid extraordinary scan lengths. The schedule was made with the early tape start feature. Wettzell was not excluded for an Intensive session since the Intensive schedule does not list an Intensive session for days 350 and 351.
