Detailed Description

Service that facilitates material scan on initialize This service outputs a ROOT file containing a TTree with radiation lengths and material thickness For an example on how to read the file, see Examples/scripts/material_plots.py.

!!! Superseeded by MaterialScan_genericAngle.h that extends this script by the possibility to use also theta (degrees), theta (radians) or cos(theta) instead of eta. !!!
