  \caption{Conditions for the correction of enhanced~$J_\nu$ at the inner
    boundary. The reference radius~$R_{\rm ref}$ is set to the radius
    of $\tau_{\rm Ross}\approx 2/3$. $R_{\rm ref2}$ refers to the
    radius where $\tau_{\rm c+l}\ge 3$. All $\tau$~values are derived
    radially from the inside outward.}
