Model parameter comparisons for each timing bin (TB) in Obs 1 (hollow circles) and Obs 2 (diamonds). The red horizontal dashed and solid lines represent the time-averaged parameter values for Obs 1 and Obs 2, respectively, and the shaded areas show the uncertainties. The TB colours are consistent with their respective spectra in Fig. 4. The model parameter is shown on the y-axis of each panel. The light purple lines (dashed for Obs 1 and solid for Obs 2) connect the TB values for each parameter in the two observations.
