Notes. Here Θs = Ts/ (msc2), 
, and 
the fluid velocity at the entrance of the diffusion region of species s, measured in Fig. 4. Also, 
is the thermal Larmor radius in number of cells with rcs = ⟨ (γvperp)2 ⟩ 1 / 2/ωcs, estimated with the formula for a Maxwell-Jüttner plasma at rest as 
(Melzani et al. 2013). The indication of sharpness is qualitative, see Fig. 4 for details.
