Notes. The first group includes fits of increasingly complete physical models, the first assuming only Lyα absorption and then adding successively metals, a Lorentzian smearing of zq, high column density systems, ionizing flux (UV) fluctuations, and the transverse proximity effect, the last corresponding to the standard fit. The next group includes two standard fits but with non-standard fitting ranges. The next group includes fits with non-standard treatment of certain parameters. The fit “HCD fixed” fixes the three HCD parameters to their values found in fits of the auto-correlation. The other fits in this group leave free parameters that are normally fixed in the fit with the fit value given in parentheses. (The fit “Gaussian” adds an additional Gaussian to describe quasar redshift smearing.) The final group includes three fits with non-standard treatments of the BAO peak. In all fits we fix bQSO = 3.87 and f = 0.97076. Errors correspond to Δχ2 = 1.
