The inequality on line 8 of page 826 is stated in the wrong direction: it should be

$$\begin{aligned} \frac{e^{\delta }}{(1+\delta )^{1+\delta }}\ge \frac{e^{-\delta }}{(1-\delta )^{1-\delta }}. \end{aligned}$$

Consequently, the multiplicative constant \(c_\delta \) that appears in Theorem 1 should be

$$\begin{aligned} c_\delta :=(1+\delta )\ln (1+\delta )-\delta , \end{aligned}$$

and the multiplicative constant \(\kappa \) in condition (1.4) should be

$$\begin{aligned} \kappa =\frac{3\ln (3/2)-1}{2+2r}. \end{aligned}$$

The authors would like to thank Lukas Meier for mentioning this error.
