The 9th VieVS User Workshop will be held at the TU Wien (Vienna, Austria) with the main part about VieVS being scheduled for September 11 to 12, 2018 (Tuesday to Wednesday). On Thursday morning (September 13, 2018) there will be an introduction to the correlation of VLBI sessions using the DiFX software correlator. The program on Thursday is optional and can be considered as an extension of the VieVS workshop with discussions about VLBI correlation.
