  Thermal conductance of a homogeneous 1D nonlinear lattice system with
neareast neighbor interactions has recently been computationally studied in
detail by Li et al [Eur. Phys. J. B {\bf 88}, 182 (2015)], where its power-law
dependence on temperature $T$ for high temperatures is shown. Here, we address
its entire temperature dependence, in addition to its dependence on the size
$N$ of the system. We obtain a neat data collapse for arbitrary temperatures
and system sizes, and numerically show that the thermal conductance curve is
quite satisfactorily described by a fat-tailed $q$-Gaussian dependence on
$TN^{1/3}$ with $q \simeq 1.55$. Consequently, its $T \to\infty$ asymptotic
behavior is given by $T^{-\alpha}$ with $\alpha=2/(q-1) \simeq 3.64$.
