Hi All, Concerning the efficiency in DCs I have a new plot- attached as T2T3Comparison.ps. The plot shows the momentum distribution of the BfsTracks found in T2-T4-T5 system (balack line) and T3-T4-T5 system (red line) in run 5650 (12 deg, 12 sequences). The plotted ratio 0.88 (number of T3-T4-T5 tracks to number of T2-T4-T5 tracks) is directly related to the ratio of T3 and T2 reconstruction efficiencies. If the derived efficiency for T3, 81%, is correct, than we get 92% efficiency for T2. I think that it is quite consistent. As I mentioned the efficiencies for the T4 and T5 are ~92% and ~72% and that is what we should expect for the rest of run at 12 deg. (if nothing will happen).
