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> }

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.tr.
  • Ex. bb.tr.vz
