Notes. From left to right columns: run name; ratio of CR to thermal pressure; CR parallel diffusion coefficient; turbulence driving wave number in units of the box length; turbulent forcing velocity; turbulence crossing time at the box scale length tcross = Lbox∕vrms; Alfvénic Mach number; critical diffusion coefficient defined as in Eq. (22). (a) X stands for the value of the forcing wave number kturb.
