healpy.pixelfunc.vec2ang¶
- healpy.pixelfunc.vec2ang(vectors, lonlat=False)¶
vec2ang: vectors [x, y, z] -> theta[rad], phi[rad]
- Parameters:
- vectorsfloat, array-like
the vector(s) to convert, shape is (3,) or (N, 3)
- lonlatbool, optional
If True, return angles will be longitude and latitude in degree, otherwise, angles will be co-latitude and longitude in radians (default)
- Returns:
- theta, phifloat, tuple of two arrays
the colatitude and longitude in radians
