Footprint of 33 map-projected images (latitude range: −50° to +30°, longitude range: +70° to +160°) superimposed on the cylindrical projection map of the shape model of 67P. The gray shading described the area on the shape model that was illuminated at 23:52:10 on 9 April 2016. The color gradient displays the overlapped area of the OSIRIS NAC images that were acquired during the fly-by on 9–10 April 2016. The color code is as follows for the overlapping: yellow shows all images, orange shows more than half of the images, bright blue is for less than half of the images, and dark blue shows none of the images. The map projection of the shape model was made with the ShapeViewer software (http://www.comet-toolbox.com/shapeViewer.html).
