We study the behavior of the tail probabilities $P(V^2<r)$ as $r\to 0$, where $V^2$ is defined by the following double sum $$ V^2 =π^{-4}\,\sum\limits_{i,j\ge 1} \Big((i+b)\,(j + δ)\Big)^{-2}\,ξ_{ij}^2,$$ where $ \{ξ_{ij}\} $ are independent standard normal random variables, and $b$ and $δ$ are constants: $b>-1,\ δ>-1$.
