The further data analysis will be based on the output data summary tapes from the event reconstruction. The size of this data sets will strongly vary for the different physics analysis carried out. Events with special physics tags will be written to separated output streams of the initial event processing. Usual reduction rated e.g. for the charm sector range in the order of 50-100 or higher at the first filter stage. This data will be analysed at CERN and at the participating institutes.
