  Encouraged by the recent real-time renormalization group results we carried
out a detailed analysis of the nonequilibrium Kondo conductance observed in an
InAs nanowire-based quantum dot and found them to be in excellent agreement. We
show that in a wide range of bias the Kondo conductance zero-bias anomaly is
scaled by the Kondo temperature to a universal lineshape predicted by the
numerical study. The lineshape can be approximated by a phenomenological
expression of a single argument $eV_{sd}=k_{\rm B}T_{\rm K}$. The knowledge of
an analytical expression for the lineshape provides an alternative way for
estimation of the Kondo temperature in a real experiment, with no need for time
consuming temperature dependence measurements of the linear conductance.
