Utilities

Index conventions, Wigner functions and rotations, evaluation at arbitrary points, and equivariance errors. The modules are as follows.

Module	Contents
s2conv.utils.rotation	Wigner d- and D-functions and rotations
s2conv.utils.evaluation	Evaluation of band-limited fields at arbitrary points
s2conv.utils.indexing	Index conventions for harmonic and Wigner coefficients
s2conv.utils.equivariance	Equivariance errors over random signals and rotations
