calc_mcilwain_l¶
- gdt.missions.fermi.mcilwainl.calc_mcilwain_l(latitude: Union[float, int, List[float], List[int], tuple, ndarray], longitude: Union[float, int, List[float], List[int], tuple, ndarray]) ndarray[source]¶
Estimate the McIlwain L value given the latitude (-30, +30) and East Longitude. This uses a cubic polynomial approximation to the full calculation.
- Parameters:
latitude – Latitude in degrees from -30 to +30
longitude – East longitude in degrees from 0 to 360
- Returns:
(float or np.array)
