[Color_transp] CT coincidence tracking efficiency; new hcana

[John Matter]

Hi all,

I checked out the most recent hcana that has changes to the tracking code.
I replayed all our coin runs with the most recent ct_replay and put them in
my ROOTfiles directory
/work/hallc/e1206107/jmatter/ROOTfiles/pass2_new_tracking

I calculated the tracking efficiency and compared it to our pass2 (hcana
pre tracking changes) root files.
/volatile/hallc/comm2017/e1206107/ROOTfiles/pass2

I see more events total that should create a track, as well as events that
do create a track. However, the proportion that create a track is lower.

Here are the cuts I used:

Should =
(P.hod.goodscinhit==1 &&
(P.dc.1x1.nhit + P.dc.1u2.nhit + P.dc.1u1.nhit + P.dc.1v1.nhit +
P.dc.1x2.nhit + P.dc.1v2.nhit) < 21 &&
(P.dc.2x1.nhit + P.dc.2u2.nhit + P.dc.2u1.nhit + P.dc.2v1.nhit +
P.dc.2x2.nhit + P.dc.2v2.nhit) < 21 &&
P.ngcer.npeSum < 0.1)

Did = (Should && P.dc.ntrack>0)
