Validate track reco

[jdkio]

We can measure the amount of true visible energy from a particle on a track / true visible energy from the particle. This has a peak at about 80% for LAr-TMS true muons, which means about 20% of the hits are missed.

We need to investigate why this is happening.

One theory is that the true endpoint isn't found. This is what I get for LAr->TMS true muons. Most are in the last plane but there's a few outside that big peak. I get about 35% outside 10cm in z.

X has an uncertainty around 10cm, which seems high too

The event display doesn't plot all hits, just hits on track. This doesn't let us know about missed hits, so it's difficult to know what's happening. So that needs to be checked
