* From the build src directory: grep -nr “rvardef*” .

* All definitions below are recorded in the following order: { <variable extension>, <Definition>, <SBS-offline designation> }

h1. Tracking Definition

* These definitions are defined in Podd. See github [https://github.com/JeffersonLab/analyzer].

h1. Calorimeters, HCal and BBCal

* HCal and BBCal share the same class so their variable definitions are the same, but with a different prefix.

** HCal variables have the prefix *sbs.hcal.*

** BBCal variables have the prefix *bb.*

* These definitions from the following source files defined in SBS-offline. See github for more information.

** SBSCalorimeter.cxx

** SBSGenericDetector.cxx
