Values of hyperparameters describing ψ as a function of detector position, also plotted as histograms above the main panels. White colour in the main panels corresponds to the median hyperparameter value. To better visualise trends, the colour bar and histogram limits only show the central 95% of the plotted values. The units on the colour bar are indicated above the panels. The vertical dashed red lines showing the median and the central 68% limits (calculated over all values) which are also shown as thick black lines in the colour bar.
