Restructuring anab::ParticleID Kirsty Duffy and Adam Lister 1

2 Introduction The current anab::ParticleID class is currently very restrictive. There are currently methods for the Chi2 algorithm and PIDA but nothing else. If you want to add a PID algorithm, this requires changing LArSoft each time! We’ve recently been doing some PID work on MicroBooNE. In the process, we have developed a new organisation of the anab::ParticleID class which is easily extendable , and should be able to hold results for any potential algorithm we could think of. Previously presented at LArSoft co-ordination meeting on 17th July 2018: have implemented suggestions and now hoping to implement new structure in LArSoft

3 Overview of new structure The change comes down to replacing all variables with a new vector of sPArticleIDAlgScores structs. Current Proposed
