giant.utilities.spherical_coordinates

This module contains helper functions for transforming from/to spherical coordinates.

Functions

radec_to_unit	This utility converts (a) right ascension and declination pair(s) expressed in units of radians into (an) unit vector(s).
unit_to_radec	This function converts a unit vector(s) into a right ascension/declination bearing(s).
radec_distance	This function computes the great-circle angular distance in units of radians between ra/dec pairs.
