h1. Replay Output Variables
{{toc}}
h1. Description
* One can search any working build of SBS-offline or Podd for “rVarDef” to find the location of these definitions.
* 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].
** THaSpectrometer.cxx
* All definitions below are accesed from the tree with the prepend *bb.*. *bb.tr*.
** Ex. *bb.tr.vz*
