Based on setC3 the number of events with reco EM cluster ET>20 GeV is similar for the filtered and unfiltered pythia samples after LT correction - compare yellow & green areas:

Hi Jan,
I processed the events in setC3 and I put the plots into the
fgt-hn-contributions drupal page. (All plots show unfiltered events on
the left and filtered events on the right).
Transverse energy spectrum for the QCD events:

Number of events passing ET>20GeV and ET>20GeV + Eta < 1.7 for QCD
