Hi, it seems to me that this D** bug was actually due to an inconsitency when producing the dataset files. So here is how I proceeded: - computed the D**+other ratio performing a 3 parameters mx fit (= 0.4286+-0.1249). - produced dataset with this ratio fixed. - computed the S/P ratio for IP > 0.20 now I was running the systematics due to S/P for this IP cut... I have a question: do I need to reproduce the D**+other ratio for each IP cuts (and also datasets for fittest) or can I use the above and just cutting on IP when computing S/P?
