Comment: in Namibia 2004, the Spiegelteam members made a mistake at night using the wrong color filters.
Daniel Verschatse helped out with his very nice color data set that we are allowed to combine it with our luminance data.
Both data set were shot in nights with poor seeing conditions. Thanks Daniel! :-)
