Fig 9. Sky Orientation of Painel do Pilão showing the cardinal directions of the largest grid image, matrix of lollipop shapes, and the beginning image at the far western edge of the outcrop.

Also depicted is the sun capture window, which was laser measured from the viewing platform at a distance of 45 meters. It visibly "captures" the sun ~18–20 days before and after the winter solstice if an observer stands on the (12-meter long) platform at least 9 meters away from, while facing, the grid image.
