This summary presents a comprehensive analysis of the data volumes associated with T1 runs from 2001 to 2003. It highlights key statistics, including the total number of runs (855) and subruns (5474) for 2002-2003, along with the number of input (1,078,136,343) and output events (145,312,442). Notably, it addresses the occurrence of bad runs and discrepancies in statistics, emphasizing the overall stability of the data. The findings provide insight into run quality and adjustments made for MSGC (Multiwire Gas Chamber) performance.

  6. Summary On the level of statistics discrepancy is around 1%! Taking into account different approaches 1% of statistics is nothing for final result discrepancy! What is more interesting – Not RUNs which are used by D and not S, or used by S and not by D, but intersection of sets for runs which are used as S, so D. D S
