Utilities related to data clustering catalogs.

Functions

cartesian_to_sky	Transform cartesian coordinates into distance, RA, Dec.
distance	Return cartesian distance, taking coordinates along position last axis.
sky_to_cartesian	Transform distance, RA, Dec into cartesian coordinates.
vector_projection	Vector components of given vectors in a given direction.

Classes

DistanceToRedshift	Class that holds a conversion distance -> redshift.
RedshiftDensityInterpolator	Class that computes and interpolates a redshift density histogram \(n(z)\) from an array of redshift and optionally weights.
