[Rivet] ATLAS ttbar+jets analysis

Hi,

	I think I need a clarification. In ATLAS_2014_I1304688.cc L.121-139 I noticed that if the _overlap variable is set true, the whole event is vetoed. I thought the action to take in such a case was to remove the overlapping object, then proceed to cut on the good final state objects (1 el/mu, >=4jets, btags, etc).

Cheers,
Riccardo

The code runs and the cut flow in the code has been completely cross-checked against standalone code running on the same data. The cut flow exactly agrees.  However, the pseudo-top distributions do not agree with those in the pseudo-top paper, despite being coded from the text of the paper and internal note.  This is under urgent investigation.
