Vertex (and kinematic) fitting
7.5. Vertex (and kinematic) fitting#
There are a number of vertex-fitting and kinematic fitter libraries interfaced and available for use in basf2.
By default, Tree Fitter is recommended even for simple single-vertex use-cases, however there are use cases where a better-performing or specialist tool is needed.
These fitters can be added to your basf2 path using a set of the convenient pre-defined python wrapper functions.
