    Previous results - May 2002



    This document is intended to provide all the information available for previous productions such that results for Quality Control studies and Productions Cross checks. Part of quality control studies include identification of missing/dead detector areas, distance of closest approach distributions (dca), and fit points distributions(Nfit). As part of production cross checks, some results in centrality dependance and efficiency are shown
