INT2 sessions Schedules and Notes prepared by Dieter Ullrich, BKG Leipzig Date of experiment: 2008 OCT 26 - 300 (eVLBI) Nominal Start Time: 07h30 UT Nominal End Time: 08h30 UT Duration: 1.0 hr Number of scans per experiment: about 20 Correlator: GSI Participating stations: Station Code KASHIM34 Kb WETTZELL Wz Tape usage and scans to be observed: See summary of schedules below Station Code WETTZELL Wz KASHIM34 Kb Tape usage and scans to be observed: See summary of schedules below Purpose ======= The project is the first implementation of a second INTENSIVE-observation routine to improve UT1-determination. The project started with regular observations each Saturday on April 12th 2003. With its regular experiments it will be both independent control and reasonable complement to the existing observation routine using baseline Wz-Kk. Since August 2004 the Wz-Ts series is augmented by regular observations on Sundays. Starting on May 21st, 2005 all sessions are carried out as eVLBI sessions. Schedule ======== The schedule was produced by Dieter Ullrich using a mixture of the automatic and the manual mode of sked version 2007Jan05 under linux. The minimum scan duration was fixed to 40 sec (before August 04 it was fixed to 120 sec). The minimum SNR on all baselines is 25 at X band and 20 at S band.
