Introduction

The tesseract package is designed to compute concentrations of simulated dark matter halos from volume info for particles generated using Voronoi tesselation. This technique is advantageous as it is non-parametric, does not assume spherical symmetry, and allows for the presence of substructure. For a more complete description of this technique including a comparison to other techniques for calculating concentration, please see the accompanying paper Lang et al. (2015).

This package allows users to:

• perform Voronoi tessellation through access to qhull routines
• measure particle distribution properties like concentration using different techniques including tessellation
• replicate the performance test presented in Lang et al. (2015)
