Let $\mu$ be a positive measure with compact support contained in $\mathbf R$, and set $$ \widehat\mu(z)=\int(z-x)^{-1}\,d\mu(x). $$ This paper studies the convergence of diagonal Padé approximants for meromorphic functions of the form $f(z)=\widehat\mu(z)+r(z)$, where $r(z)$ is a rational function.
