We comment on the effect this change produces on the numerical estimates of the bottom quark pole mass $m_b$, the strong coupling constant $\al_s$ and the Cabibbo-Kobayashi-Maskawa matrix element $|V_{cb}|$ obtained in our papers [1,2].3 pages, LaTeXHigh Energy Physics - PhenomenologyComment on ``Next-to-next-to-leading order vacuum polarization function of heavy quark near threshold and sum rules for $b \bar b$ system'' and ``Next-to-next-to-leading order relation between $R(e^+e^-\to b\bar b)$ and $Γ_{\rm sl}(b\to clν_l)$ and precise determination of $|V_{cb}|$''text
