The original nadir image consists of 2048 x 1532 pixels, each pixel averagely representing an area of 2.93m x 2.93m, as calculated from . It has been rotated by 180 degrees to get north to the top of the photo and another 27 degrees to get it upright. Then a section of 1000 pixels width and 1000 pixels height has been taken from it. To illustrate the impression mentioned, the margins of the slopes have been traced by painting arcs and lines in this section of the 2007 image from MRO. These painted arcs and lines are parts of circles and squares constructed with software onto the photo by specifying center, radius, start angle and end angle or by dragging the edges under retained proportions until they seem to fit. Looking at the image, one’s eye clearly notices six slope margins which have been traced.
They are from top to bottom:
At the right or eastern side the slopes do not show such distinctive margins like the western side of the mountain does. Because of this circumstance, no attempts have been made to localize slope margins on the eastern side. Additionally, two axes have been drawn illustrating axial symmetry for the northern arc and southern arcs. The axis from north to south mirrors the western side to the east and makes a guess, where straight slope margins once might have been.Based on this picture three following elementary properties of the mountain can be fixed: Its length takes 920 pixel in the image, representing 2692 m (1.673 miles) ~ 2.7 km, and its width takes 630 pixel in the image, representing 1885 m (1,171 miles) ~ 1.9 km, giving an aspect ratio of 1.428 for length to width. The square of the aspect ratio is nearly 2 (1.428 x 1.428 = 2.04), so the aspect ratio is near √2.
