Detailed Description

Functions to convert Miniball angles read from the frame.

Miniball Geometry class

A geometry class that converts cluster angles read from the Miniball frame into real-life angles for the analysis. You can have theta and phi angles of the centres of each cluster, crystal and segment in frame geometry or true/beam geometry.
