Mattione Reconstruction Uncertainties

Introduction

• I would like to update the current reconstruction uncertainties to improve the particle-ID algorithms and support the kinematic fitting analyses. Right now the tracking uncertainties are yielding dubious chi-squares and kinematic fits with too many events at low-confidence levels. Also, the timing uncertainties used for calculating the particle-id FOM are one-size-fits-all numbers, instead of incorporating any momentum or energy dependence.

• I would like to fix these problems with the reconstruction uncertainties, and do so in a framework that can be used for experimental running. That way we will get a better understanding of the eventual experimental reconstruction uncertainties, and we won't need to re-write the framework

replace some of these ad-hoc uncertainties uncertainties at the post-calibration level so that we can improve
