| Quick and simple test just now. I will not plot everything out in the categories, I do not have the time to waste. Just get a feel for what is going on. | |||||||||
| Line: 14 to 17 | |||||||||
| Old tight ID in 2_2 gives 0.73% passing in the ZJets sample that I re-ntupled myself (1000 events). The tightIdMinMatteo gives 0.70. Similar performance, hypothesize difference due to H/E being less good than before, despite cutting tighter. | |||||||||

| For reference, the old cuts for H/E and SigmaEtaEta . First row is barrel second is endcap. Each entry is for a different "class". Summary: H/E is tightened, sigmaEtaEta is not changed much. | |||||||||

| What has changed: The weighting factor changed from 4.2 to 4.7 or the other way round, I forget which. The reason I have no idea. I hear it on good authority it is basically made up on the spot for no good reason. | |||||||||

SIGNAL | |||||||||

| < < | H/E | ||||||||

| What has changed: H/E used to be calculated as the ET of the HCAL rechits in a cone of 0.3 about the super cluster to the ET of the super cluster. In 2_2 the "H" changed to ET of the calo tower than has highest ET at depth 1 that is within some distance of the electron, either that or just the closest calo tower. Doesn't matter which it was, because both are the wrong thing to do and degrade the performance of the variable. The optimum was found to be the sum of the hcal energy in a cone of 0.15. This will be done in 3_X. | |||||||||

| Here just a quick check. The "N-1" here is with SigmaEtaEta . "Signal" sample only plotted. Nothing should have changed much and indeed that seems to be the case. | |||||||||
