As was done for the soft muons earlier, I compare the shapes of the pTrel and d0 distributions for soft electrons in the TCE-triggered sample in MC and mistagged data.

Here is pTrel:

And here is d0:

The shape of the mistag distribution is clearly different than the W+light MC in both variables.  The mistag response needs to be changed.

Next I try to do the simultaneous fit to the pTrel and d0 distributions for the soft electron samples in both the TCE and CMUP/CMX samples.  Here is the TCE fit.

And here is the combined CMUP/CMX fit

We see an excess at large |d0| in both samples.
