Hi Beate and Florencia, I learned a lot from reading CDF-7543. I did find a few typos which could be corrected, if you haven't submitted the article yet. p25L9: "that edge which is more distant" p37L4: "two halves" p45L3: "correction aims" p45L6: "has been optimized" p45L16: italicize "a priori" p49L24: "event" p50Fig23: "data have" p53L35: The vertex finding efficiency is definitely finite, but I think you mean here that the efficiency is not quite 1. p56L7: "Figure 28 shows no" p60L1: "annulus defined by radii" p64L23: "background" p65L1: " the n-dependent" p65L8: "Tables 4 and 5" p66L5: "data generally lie" p66L7: "Herwig" And I have two questions: p48L10: What does E^\pm mean, and why is \Delta E defined that way? p49L36: Is R(p) actually fixed for these plots? What is it fixed to for the charged hadrons? I'll just come by your office and you can explain to me... Congratulations! Jason
