Abstract

Comparing simulation and data histograms is of interest in nuclear and particle physics experiments; however, the leading three-dimensional histogram comparison tool available in ROOT, the 3D Kolmogorov-Smirnov test, exhibits shortcomings. Throughout the following, we present and discuss the implementation of an alternative comparison test for three-dimensional histograms, based on the Energy-Test by Aslan and Zech. The software package can be found at http://www-nuclear.tau.ac.il/ecohen/.
