It's the one that has the Run I pT spectra in it. For some reason, I get negative bin-contents throughout. I guess the likely culprit is this line in finalize: <blockquote>scale(_hist_pt, crossSectionPerEvent()/millibarn); </blockquote> Is this supposed to work? If there is no uick fix, do you think it's ok to normalise to the ref-histo area in this case? Cheers, Holger </body> </html>
