ZEUS data format: Common Ntuples

The ZEUS analysis model before the end of 2012 has been based on Mini Data Summary Tapes (MDST) and contained a lot of external dependencies, therefore it was not intended to be maintained when the available manpower was reduced. Therefore the ZEUS analysis software was used to create common-usage ntuples (real and MC data). The ROOT-based Common Ntuple (CN) content has been iterated over the last few years. By their structure CN are either simple ROOT files with TTree objects only or PAW files with simple trees. They contain the necessary information to perform all ongoing and planned future analyses; all ongoing and most of the recently published analyses actively use them.
See: ZEUS DESY Common ntuple page.
