My data were normalized to approximately match Olaf's 80lux TA isoline size. For the purpose of the comparison (the 4 images on this page): values of isolines (e.g., ..,80,70,60,..), headlight height (0.7m), aim distance (10m) — are as Olaf Schultz uses. Isolines not colored. Colormap is (almost) same.
