chaosmagpy.coordinate_utils.dipole_tilt¶
- chaosmagpy.coordinate_utils.dipole_tilt(time, dipole=None)[source]¶
Compute the dipole tilt angle in degrees.
- Parameters:
- timendarray, shape (…)
Time in modified Julian date.
- dipolendarray, shape (…, 3), or tuple of ndarrays, optional
Dipole coefficients. Accepted input is a single array with the dipole coefficients \(g_1^0\), \(g_1^1\) and \(h_1^1\) in the trailing dimension; or a tuple of two arrays, where the first array is the co-latitude of the geomagentic north pole and the second is its longitude; or a tuple of three arrays, one array for each dipole coefficient in the natural order. Defaults to the SH coefficients in
basicConfig['params.dipole'].
- Returns:
- tiltndarray, shape (…)
Dipole tilt angle in degrees.
