chaosmagpy.coordinate_utils.igrf_dipole¶
- chaosmagpy.coordinate_utils.igrf_dipole(epoch=None)[source]¶
Compute unit vector that is anti-parallel to the IGRF dipole.
The vector points towards the geomagnetic north pole (located in the Northern Hemisphere).
- Parameters:
- epoch{‘2015’, ‘2010’}, optional
Epoch of IGRF-12 (2015) and IGRF-11 (2010). Epoch 2015 of IGRF-12 is used by default.
- Returns:
- dipolendarray, shape (3,)
Unit vector pointing to geomagnetic north pole (located in Northern Hemisphere).
