EUROPE-5/95 (EUROPEAN Geodetic VLBI Network session 5/95) Notes prepared by Axel Nothnagel, University of Bonn Geodetic Institute Date of experiment: 1995 November 9 Nominal start time: 22h00 UT Nominal end time: 22h00 UT on November 10 Duration: 24 hrs Participating stations: Station Code Station Code # of tapes # of obs Wettzell V 2 (HDT) 243 Madrid M 2 (HDT) 229 Matera I 4 (HDT) 239 Onsala T 4 (HDT) 241 Medicina B 2 (HDT) 259 Noto S 2 (HDT) 259 Schedule name: EUROPE5.SKD on CDDIS for all stations except DSS65 DSN file name: Correlator: Bonn Purpose ======= The purpose of this experiment is to determine station coordinates in the northern 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 station positions of DSS65, Medicina, Matera, Noto and Onsala with Wettzell as the reference station. The minimum SNR on all baselines is 20 at X band and 15 at S band. A large number of observations was given priority of higher SNR limits. The schedule was made with the early tape start (15 seconds) feature. Wettzell was excluded for IRIS-Intensive between 19h20 - 20h50 on Nov. 10. Procedures ========== The frequency sequence, EUR-SX, used for the last EUROPE experiments will also be used for this experiment although it was designed for the Italian stations. Using this frequency sequence in all experiments of the EUROPE series avoids confusions. Channel Sky Frequency ======= ============= X-band 1 8210.99 2 8220.99 3 8250.99 4 8310.99 5 8420.99 6 8500.99 7 8550.99 8 8570.99 S-band 1 2212.99 2 2222.99 3 2237.99 4 2267.99 5 2292.99 6 2297.99 Correlation =========== This experiment will be correlated at the Bonn Correlator with all baselines being correlated.
