Error evaluation of the intensity predictions. Left: Log-density plot of pixel-to-pixel correspondence between the actual and predicted values. The red lines delimit certain error levels. Middle: Error estimate of the predictions as a function of actual intensity (typical width of the distribution from the left panel). Right: The distribution of the worst predictions. The full lines show pixel counts while the dashed lines show the pixel densities. The dashed lines are in different colour shades for better visibility.
