spacepy.empiricals.getLmax¶
- spacepy.empiricals.getLmax(ticks, model='JKemp', dbase='QDhourly')[source]¶
calculate a simple empirical model for Lmax - last closed drift-shell
Uses the parametrized Lmax from: Koller and Morley (2010) ‘Magnetopause shadowing effects for radiation belt models during high-speed solar wind streams’ American Geophysical Union, Fall Meeting 2010, abstract #SM13A-1787
- Parameters:
- ticksspacepy.time.Ticktock
Ticktock object of desired times
- modelstring, optional
‘JKemp’ (default - empirical model of J. Koller)
- Returns:
- outnp.ndarray
Lmax - L* of last closed drift shell
