chaosmagpy.coordinate_utils.geo_to_base¶
- chaosmagpy.coordinate_utils.geo_to_base(theta, phi, base_1, base_2, base_3, inverse=None)[source]¶
Transform spherical geographic coordinates into spherical coordinates of a rotated geocentric coordinate system as given by three base vectors.
- Parameters:
- thetafloat or ndarray, shape (…)
Geographic colatitude in degrees.
- phifloat or ndarray, shape (…)
Geographic longitude in degrees.
- base_1, base_2, base_3ndarray, shape (3,) or (…, 3)
Base vector 1 through 3 resolved into components with respect to GEO.
- inversebool, optional
Use inverse transformation instead, i.e. transform from rotated to geographic (default is False).
- Returns:
- thetandarray, shape (…)
Colatitude in degrees \([0^\circ, 180^\circ]\) of the rotated coordinate system.
- phindarray, shape (…)
Longitude in degrees \((-180^\circ, 180^\circ]\) of the rotated coordinate system.
