Parameters estimated directly by MCMC sampling (Z, nH, αUV and |${\it N}_\mathrm{H\,\small {i}}$|) and other derived parameters for the eight components we model. The metallicity has a flat prior between −3 and 0.5, the number density has a flat prior between −4 and 0, and αUV has a flat prior between −3 and 2. Bold indicates that value has an additional prior applied: for αUV this is a Gaussian distribution centred on αUV = −0.25 with σ = 0.5, and for |${\it N}_\mathrm{H\,\small {i}}$| it is the |${\it N}_\mathrm{H\,\small {i}}$| measurement in that component. The uncertainties are 1σ, marginalized over all other parameters, and so take into account covariances among the parameters. We include an additional 0.3 dex systematic uncertainty in nH due to the unknown normalization of the incident radiation field. This is propagated to all quantities which are derived from nH: D, mass and P/k. For these quantities, the uncertainty without including this nH systematic is shown in parentheses.
