During recent analysis I noticed a some differences in my results from ROOT and python (using pyutils).
I'm still finalizing the ROOT side but one obvious difference is how we do the CRV-Trk cuts which is quite different. We should settle on a standrd, looping in Natalie, Sam and Yuri.
I also have some differences in how I cut on the trk parameters, this could be a problem with my code or another difference in the utils. I will finalize that study and post here to confirm.
In general we want to move to using the extrapolations instead of the old trk pars. This is a more detailed study. Let's get the current cuts aligned first.
