spheres.coordinates.xyz_sph

spheres.coordinates.xyz_sph(xyz)

Converts cartesian coordinates \((x, y, z)\) to spherical coordinates \((\theta, \phi)\). We use the physicist’s convention:

inclination: \(\theta = \arccos{\frac{z}{\sqrt{x^2 + y^2 + z^2}}} \in [0, \pi]\)

azimuth \(\phi = \arctan{\frac{y}{x}} \in [0, 2\pi]\)

Parameters

xyz (list/np.ndarray) – (List of) Cartesian coordinates.

Returns

sph – (List of) Spherical coordinates.

Return type

np.ndarray
