VertexFinder

Analyses ability to find an event vertex position given two tracks.

  • Input: 3D rb::Tracks
  • Output: rb::Vertex

Usage

nova -c vertexfinderjob.fcl -s <sourcefile>.root

Technical description

The algorithm is getting initial directions of input tracks to calculate the mid point of each DOCA (Distance of Closest Approach) for all combinations of tracks.
Currently only returns a reconstructed vertex position distribution plotted in a histogram. Will eventually return a reconstructed rb::Vertex object.
