\caption{\label{table:all}We list $f\times 10~000$ to improve the clarity of the
  table. $\sigma(f)$ refers to the Gaussian errors (those derived from
  the $\chi^2$ curvature matrix).  The average values are quoted as
  $\langle f \rangle \pm \sigma_1 (\sigma_2)$ (see text for details),
  and exclude the coadded spectra. Equivalent widths for
  $^{12}$CH$^+$, $W_\lambda$, are given in m\AA. The stars select the
  measurements included in the combined values of $R$; the selection
  are discussed in the text.        }
