A Python package to compute bond orientational order parameters as defined by Steinhardt Physical Review B (1983) doi:10.1103/PhysRevB.28.784.

Steinhardt's bond orientational order parameter is a popular method (>20k citations of the original paper) to identify local symmetries in an assembly of particles in 3D. It can be used in particle-based simulations (typically molecular dynamics, brownian dynamics, monte-carlo, etc.) or in particle-tracking experiments (colloids, granular materials) where the coordinates of all particles are known.
