boos@theory.sinp.msu.ru via lpsc.in2p3.fr Feb 8 Dear Sabine, As we discussed shortly there is one point which worries me. In fact in experimental analyses there are hidden details. Of course, not all of these details are needed to be known for the community out of the concrete experimental collaboration. However what would be good to know in addition to what was mentioned are details of background modeling, especially out of signal regions. Namely which generators with which exactly tunings and parameters were used, details of matching procedures, references on Monte-Carlo samples with may be names of people who prepared samples with whom one may communicate for further details, how well comparison with data was, whether or not some additional normalization factors were used etc. Best wishes, Edward
