Discretization and parameterization:

Most energy is transported in the forward direction, hence it make sense to have smaller bins in the forward direction.

36 bins

201 bins

106 bins (default in Oncentra, Monaco)

Discretization into angular bins causes 1/ r 2 dependence in parameterization to vanish
