FYI i've just successfully upgraded server hardware, actually doubled the RAM memory and SDD (storage) size.
Analemma Square at Rock Gate
If you open the West Iron Door 90 degrees (as it's usually found during business hours), then the sun on the door is in a square with the similar carving out of stone on the Western edge of the King's Stone. This shows the CAD mapping of A and B and below will be pics of both:
A: Analemma on West Iron Door
B: Analemma on West edge of King's Stone:
The radius of the circle or edge of the square seems to be about 726 inches.
