W 2012 comparison of SL13b and Fall2012 productions
2012 W-stream was re-produce with SL13b .
Jinlong Zhang run W code over new muDst and prepare our standard movies for the barrel & endcap Ws, new and old production:
However, one plot (fig 1) shows unexpected problem. For the endcap we gain extra 40 Ws (30% increase) but the charge separation (Q/PT vs. ET) degraded in a visible way.
Fig 1.
Jinlong constructed new histogram file being the difference between SL13b and the old production. He made the PDF movie just for the excess events in SL13b:

It start to be interesting, see my comments in attachement 1.
