☀️ Pantheon Oculus: Sun Altitude, Beam Path and Floor or Wall Patch (2D section)

Vertical section through the Pantheon rotunda along the sun azimuth. Choose the hour, the day of the year and the oculus diameter, and see where the sunbeam lands, how much power it carries, and when it reaches the floor. Same latitude, declination formula and dimensions as the 3D lab, with four in-page numerical checks.
