# LArFlow Reconstruction tools

This code is for track, shower, and vertex reconstruction using larmatch points as inputs.

## strategy

We perform a merge/break loop with the clusters

Prep stage

* first make clusters using dbscan
* select clusters of minimum size

Break/Merge loop

* next get pca for all clusters
* break individual clusters at point greatest distance to first pca-axis
* re-pca broken clusters
* merge clusters if on same line: pca-axis intersects at point between. point between some min distance from line between cluster ends.
* reform cluster and re-pca
* stop when no more clusters merge or break
