Fig. 6
Spectral index, δ, calculated from the mean electron flux shown in Fig. 5 for looptop (left) and footpoint (right). The grey confidence strip shows the possible range of δobs for the fit (
and 
).
Orange triangles are the δ
obtained from fitting the simulated ⟨nV F(E)⟩
between 25 and 50 keV. The blue diamonds show the predicted spectral index from the leaky-box approximation.
