Query: Comment on `The Newtonian force experienced by a point mass near a
  finite cylindrical source'   We compare the computation times and precisions of three expansions for the
gravitational potential. The evaluation of the series by Selvaggi et al (2008
\textit{Class. Quantum Grav.} \textbf{25} 015013) is time-consuming to be
applied to the gravitational constant ($G$) or STEP experiments.
