 assuming for the moment that $\Omega={\mathbb R}^d$ -- which is
 of course not the case, but we'll ignore the small difference in

+Thus, we choose $\alpha_k=\left(R^d\sqrt{\pi^d}\right)^{-1}$ for all, and
 $R=0.1$. This $R$ is small enough that the difference between the
 exact (infinite) integral and the integral over $\Omega$ should not be
 too concerning.
