A good series of runs. 1) There have been no noticeable trigger errors showing up in ACQCOPY stats. Some CDC inefficiency for run 34844 (96%) 2) For runs 34838 and 34842 in the trigger matrix appearing in the RECON stats file there seems to be no MUON trigger. But the matrices in the FILTER job seem normal so that probably only means that no muon-triggered events were reconstructed ... Both datasets are sizable. 3) A few comments about CDC displays: first, in several events appears that one or more tracks have been missed, see for instance 34838/587, 34840/57, 34841/126,34841/94,34845/127 plus several other doubtful cases. Second, sometimes one can see several hits aligned with a fitted track but starting *before* the track hitself: like if only a part of the hits left by a track had been fitted. See 34841/126 or 34843/311. 4) For event 34841/94 it looks like several tracks in the upper left part of the event left no hits in the VXD. Were they out along Z? 5) At 7:45 the out from ZCHKDAY is still missing. It will go into tomorrow's report... Bye, Sandro Calcaterra
