INT3 sessions e-VLBI INTensive <<<<< J17317 (doy 317) >>>>> Schedules and Notes prepared by Arno Mueskens , IGG University of Bonn Date of experiment: 2017, Nov,13 Nominal Start Time: 07h00 UT Nominal End Time: 08h00 UT Duration: 1.0 hr Correlator: BONN Participating stations: SEHSAN25 Sh Wettzell Wz Wettz13N Wn NYALES20 Ny Purpose ======= The project is the first implementation of a third INTENSIVE-observation routine to improve UT1-determination. The project started with regular observations each Monday on August 27th 2007. With its regular experiments it will be both independent control and reasonable complement to the existing observation routine using baseline Wz-Kk, Wz-Ts The goal is to bring up final processed data in less than a few hours to the IVS data centers. Schedule ======== The schedule was produced by using a mixture of the automatic and the manual mode of the actual sked version. The minimum scan duration was fixed to 15. The minimum snr was set to 24/23 for all baselines.
