EUROPE-90 (EUROPEAN Geodetic VLBI Network session No. 90) 2007 Nov. 22-23 doy 326-327 Institute for Geodesy and GeoInformation of the University of Bonn, Germany Nominal start time: 2007-326-1200 UT Nominal end time: 2007-327-1200 UT Duration: 24 hrs 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. No time second modulo is applied. The sky coverage for all stations were optimized. The minimum SNR on all baselines is at X band and at S band different. ATTENTION to all participate network stations ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! We have a new and different frequence setup for all stations! Please be carefully and setup the recording mode as discribed in the schedule and as well as in this Experiment INFO file. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! e-VLBI Transfer =============== We try to use e-VLBI data transfer with the following participating stations Mh Ny On Wz Session Notes session: euro90 =========================================================== Parameter values for experiment EURO90 Experiment description: EUROPE-90 Scheduler: IGG/am Correlator: BONN Nominal start: 2007-326-12:00:00 Nominal end: 2007-327-12:00:01 Current yyyyddd: 2007326 (2007.89) ( 14427 MJD, THUR 22NOV.)
