Figure 6: Mapping relations between L and L* for six outer radiation belt passages.
From: Ultra-low-frequency wave-driven diffusion of radiation belt relativistic electrons

Mapping relations (circles colour-coded according to the time) are calculated every 300 s in the TS04D geomagnetic field model. (a,b) Mapping relations at two different local pitch angles 70° and 40°, respectively. The dot-dashed and dashed lines are overplotted to identify the variation of the mapped L with time for the fixed L* near the slot region. Similar characteristics can be found in the mapping relations at the other local pitch angles.
