\caption{The computed broadening data.  The entire table is available only
 electronically at the CDS; a short extract is provided here as a guide to its form.  The table presents for each line:  the species as described by the packed parameter $Z+0.01(Z-N)$ where~$Z$ is the atomic number and~$N$ is the number of electrons, the air wavelength $\lambda_{\rm air}$, the $J$ quantum numbers for the lower and upper states $J_{\rm low}$ and $J_{\rm upp}$, the energies of the lower and upper states $E_{\rm low}$ and $E_{\rm upp}$, the line broadening cross-section $\sigma$ for a collision speed of $10^4$~m~s$^{-1}$, the dimensionless velocity parameter $\alpha$, and the log of the line width (FWHM) per perturber at a temperature of $10^4$~K.  Further, the cross section and velocity parameter computed using the approximation $E_{\rm p}=-4/9$~au are given, $\sigma_{4/9}$ and $\alpha_{4/9}$.\label{tab:lines}}
