chaosmagpy.coordinate_utils.transform_vectors¶
- chaosmagpy.coordinate_utils.transform_vectors(theta, phi, B_theta, B_phi, time=None, reference=None, inverse=None, dipole=None)[source]¶
Transform vectors resolved into components in USE (Up-South-East) at given spherical geographic coordinates (GEO) to components in USE into components with respect to a rotated geocentric coordinate system.
- Parameters:
- thetafloat or ndarray, shape (…)
Geographic colatitude in degrees (GEO).
- phifloat or ndarray, shape (…)
Geographic longitude in degrees (GEO).
- B_thetafloat or ndarray, shape (…)
Colatitude vector components (GEO).
- B_phifloat or ndarray, shape (…)
Azimuthal vector components (GEO).
- timefloat or ndarray, shape (…)
Time given as modified Julian date, i.e. with respect to the date 0h00 January 1, 2000 (mjd2000). Ignored for
reference='mag'.- reference{‘gsm’, ‘sm’, ‘mag’}
Target coordinate system.
- inversebool
Use inverse transformation instead, i.e. transform from rotated coordinates to geographic (default is False).
- dipolendarray, shape (3,), optional
Dipole spherical harmonics \(g_1^0\), \(g_1^1\) and \(h_1^1\). Defaults to
basicConfig['params.dipole'].
- Returns:
- thetandarray, shape (…)
Colatitude in degrees \([0^\circ, 180^\circ]\) of the rotated geocentric coordinate system.
- phindarray, shape (…)
Longitude in degrees \((-180^\circ, 180^\circ]\) of the rotated geocentric coordinate system.
- B_thetafloat or ndarray, shape (…)
Colatitude vector components with respect to the rotated geocentric coordinate system.
- B_phifloat or ndarray, shape (…)
Azimuthal vector components with respect to the rotated geocentric coordinate system.
