INT2 sessions Schedules and Notes prepared by Dieter Ullrich, BKG Leipzig Date of experiment: 2013 SEP 22 - 265 (eVLBI) Nominal Start Time: 06h00 UT Nominal End Time: 07h00 UT Duration: 1.0 hr Number of scans per experiment: about 24 Correlator: GSI Participating stations: Station Code KOKEE Kk NYALES20 Ny 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. Schedule ======== The schedule was produced by Dieter Ullrich using a mixture of the automatic and the manual mode of sked version 2011May24 under linux. The minimum scan duration was fixed to 30 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.
