Variable absorption line equivalent widths suggest substantial contamination by wind line features. This variability and limited signal-to-noise ratio hindered accurate continuum definition and prevented measurement of a high quality radial velocity curve. Nevertheless, the best data indicate a radial velocity amplitude <jats:inline-formula> <jats:tex-math> <?CDATA $\leqslant 40\;{\rm km}\;{{{\rm s}}^{-1}}$?> </jats:tex-math> <?MML <mml:math> <mml:mo>≤</mml:mo> <mml:mn>40</mml:mn> <mml:mspace width="0.25em"/> <mml:mi>km</mml:mi> <mml:mspace width="0.25em"/> <mml:msup> <mml:mrow> <mml:mi mathvariant="normal">s</mml:mi> </mml:mrow> <mml:mrow> <mml:mo>−</mml:mo> <mml:mn>1</mml:mn> </mml:mrow> </mml:msup> </mml:math>?> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="apj511886ieqn4.gif" xlink:type="simple" /> </jats:inline-formula> for the He <jats:sc>ii</jats:sc> lines and substantially lower for H <jats:sc>i</jats:sc>.
