In a recent Letter, we derived a very accurate and fast new algorithm for
numerically inverting Laplace transforms, which we used in obtaining gluon
distributions from the proton structure function $F_2^{\gamma p}(x,Q^2)$. We
numerically inverted the function $g(s)$, $s$ being the variable in Laplace
space, to $G(v)$, where $v$ is the variable in ordinary space. We have since
discovered that the algorithm does not work if $g(s)\rightarrow 0$ less rapidly
than $1/s$ as $s\rightarrow\infty$, e.g., as $1/s^\beta$ for $0<\beta<1$.
