EUROPE-42 (EUROPEAN Geodetic VLBI Network session 2/98) Schedule and Notes prepared by Axel Nothnagel, University of Bonn Geodetic Institute Date of experiment: 1998 April 20 Nominal start time: 12h00 UT Nominal end time: 12h00 UT on April 21, 1998 Duration: 24 hrs Correlator: Bonn Participating stations: Station Code Crimea Sm Matera Ma Medicina Mc Noto Nt Ny Alesund Ny Onsala 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 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. Crimea, Yebes and TIGO-A were scheduled in tag-along mode with a "maximum scan number" approach in order to be prepared for a short-notice drop-out of the stations. The minimum SNR on all baselines is 24 at X band and 16 at S band. The schedule was made with the early tape start (15 seconds) feature. Wettzell was spared for IRIS-Intensive between 110-1420 and 110-1615 Procedures ========== The frequency sequence, EUR2-SX, used for the last EUROPE experiment will also be used for this experiment.
