chaosmagpy.coordinate_utils.basevectors_mag¶
- chaosmagpy.coordinate_utils.basevectors_mag(dipole=None)[source]¶
Computes the unit base vectors of the central-dipole coordinate system (sometimes referred to as MAG) with respect to the standard geographic coordinate system (GEO).
- Parameters:
- dipolendarray, shape (3,), optional
Dipole spherical harmonics \(g_1^0\), \(g_1^1\) and \(h_1^1\). Defaults to
basicConfig['params.dipole'].
- Returns:
- mag_1, mag_2, mag_3ndarray, shape (3,)
MAG unit base vectors resolved into components in GEO.
