[Color_transp] Quick question

[John Matter]

Regarding the space point criterion, the denominator in the efficiency calculation (pscinshouldh) does not change as I vary the criterion. The only DC tracking quantities it uses are the planes’ nhits which hcana reconstructs prior to space point formation. So the increase in efficiency is indeed due to an increased number of events that have P.dc.ntrack>0

I’m wondering now if the per-event number of tracks, space points, or stubs gets funky for small values of this parameter. I’m teaching from 2 to 6 but I will take a look after that
