Detailed Description

Material-dependent data for Urban MSC.

UrbanMsc material data (see UrbanMscParams::calc_material_data) is a set of precalculated material dependent parameters used in sampling the angular distribution of MSC, \( \cos\theta \), and in the step limiter. The coefficient vectors are used in polynomial evaluation.
