Table 1: 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.
Continuum: $\tau_{\rm c}(R_{\rm ref}) $ $\le$ 10
Local $\chi$: $\chi(1)(R(2)-R(1)) $ $\le$ 6
Compare line to continuum: $\tau_{\rm c+l}(R_{\rm ref2})$/ $\tau_{c}(R_{\rm ref2}) $ $\ge$ 3
Compare local to average $\chi$: $\tau_{\rm c+l} /
(\chi(1)(R_{\rm ref} - R(1))) $ > 1
