Hi Pedro,

Thanks for the plots - nice job! They all make perfect sense to me. Waiting for the likesign distributions now...

It would be also nice to have distribution of multiplicities of various objects in the event:

N_lepton (pT > 10 GeV, |eta| < 2.5)
N_jet (pT > 15 GeV, |eta| < 2.5)
N_e
N_mu - sanity check
N_gamma (pT > 15 GeV, |eta| < 2.5) - expect very few
N_jet, for events with 1 lepton, 2 leptons

as well as fractions: N(e+e+ + e-e-)/N(e+e-); N(e+u+ + e-u-)/N(e+u- + e-u+).

Finally, let's look at the overall variables: HT = \sum ET(jet), LT = \sum ET(leptons), and ST = HT + \sum ET(leptons).
