p = p from outer helix of track (global if available, primary otherwise)

Wiki MarkupBSMD\[E,P\] total ADC = total ADC of 11 strips underneath central tower

Of the 217,866 tracks, 150,605 were associated with a tower hit more than 2.5 sigma above pedestal.

...

At this point, there's no clear E/p peak so things are looking a little troubling.

However, in the BSMDP total ADC spectrum there is a clear peak at the saturation boundary, which should correspond to electrons. Wiki Markup

I then apply a cut on BSMDP total ADC > 800.

This leaves only 3,160 tracks, put gives a very significant E/p peak around 10.19.

When I look at BSMDE total ADC vs E/p, I see that the remaining background is below around 500 ADC, so I add another cut there and remove the rather strong cut on BSMDP.

I'm left with 20,100 and a very strong E/p peak at just above 1.

This band in the upper right looked a little peculiar to us, but we found that it corresponds to the L2 trigger threshold, which was at \ ~13GeV E_T (the L0 threshold is also visible):

I also looked at the relation between energy in the tower cluster and the BSMD(E,P) ADC totals:
