Physical diffusion coefficients for M_s ≃ 10 turbulence, adopting L_box = 1 pc. The left and right panels show M_A ≃ 5 and M_A ≃ 10, respectively. Solid and dashed curves denote D_∥ and D_⊥; blue and red denote solenoidal and compressive forcing. Shaded bands indicate representative diffusion ranges inferred for the Cygnus Bubble, the Geminga halo, and the V4641 Sgr microquasar.
