One- and two-dimensional marginal posteriors for our astrophysical parameters and derived ${\overline{T}}_{21}$ at z = 17 resulting from different inferences. The plotted parameter ranges corresponds to their respective prior ranges. Blue and red contours and curves show results for our highest evidence model (seven FG terms, with calibration residuals) and lowest evidence model (four FG terms, no calibration residuals), respectively. Posteriors for the Narrowf_esc, 7 pseudo likelihood inference from Appendix A are shown in green. Dark and light shaded contours represent 68% and 95% confidence intervals, respectively. The headings above the panels show 95%C.I. for the highest evidence model.
