\caption{Mode frequencies of HD 49933, returned by the \emph{Reference}
  fit. Data marked with filled circles indicate where at least six of
  the seven fitters agreed on the value of the parameter to within
  $1\sigma$. Details are given in those cases where disagreement was
  noted at $>$$1$$\sigma$.}
