Integrability of Gaussian sums
It is a standard fact from the theory of Gaussian processes (see e.g. the Ledoux-Talagrand book)
that if $X_s$, $s \in S$, is a (centered) Gaussian process such that
$Z = \sup_s X_s$ is finite almost surely … Hence here $\sigma^2 = \sup_\alpha \langle \Sigma \alpha, \alpha \rangle$
where $\Sigma$ is the covariance
matrix of the Gaussian vector $X = (X_1, \ldots, X_n)$. …
