Introduction

We would like to make sure to propagate tracks from Robert Johnson's cosmic-ray track finder to the the new ACD recon.

Implementation

AcdReconV2 appends the cosmic-ray track collection to the end of the primary track collection incrementing the track index by 100. The original merit variables added by Robert Johnson to the old AcdValsTools have been transposed into Acd2ValsTool. These cosmic-ray (CR) variables are broken into two sets: 1) CR variables which pick the "best" CR track for vetoing the event, 2) CR1 variables, choosing the cosmic-ray track with the most hits.

Validation

I've run a few streams of diagnostic muons and all gamma with the CR track finder turned on. It appears that the all of the Acd2CR variables are being filled. I look at a few variables in a bit more detail. Specifically I show comparisons between the distance to active tiles and the energy deposited in active tiles between the cosmic-ray tracks, the tree-based tracks, and the MC truth.
