cartesian_from_spherical¶
- rubin_sim.utils.cartesian_from_spherical(longitude, latitude)¶
Transforms between spherical and Cartesian coordinates.
@param [in] longitude is a numpy array or a number in radians
@param [in] latitude is a numpy array or number in radians
@param [out] a numpy array of the (three-dimensional) cartesian coordinates on a unit sphere.
if inputs are numpy arrays: output[i][0] will be the x-coordinate of the ith point output[i][1] will be the y-coordinate of the ith point output[i][2] will be the z-coordinate of the ith point
All angles are in radians
Also, look at xyz_from_ra_dec().
