The Sun is positioned exactly 200 cubits from the Aphelion position and the interactive drawing shows the 200 cubit long line drawn from the projection of the bend point in the hexagonal rod down the gallery. The Sun is not just marked off as the end point of this line in the drawing, but is drawn as a scale model of the Sun by using the scale that can be calculated when placing the Sun 200 cubits away from the Earth's Aphelion position. If you zoom in on the Sun (click and hold) you can see the small circle that marks the center of the Sun, and a much larger circle which is a scaled drawing of the Sun.
From the basic analysis of the gallery it is known that the length of 200 cubits is related to 1 radian of angular measure and so if the Sun has been placed 200 cubits down the gallery bench line you would expect that somewhere in this construction there should be a line that is at 1 radian angle.
A line can be constructed from the Sun at an angle of exactly 1 radian from the vertical back up to the central Y axis of the pyramid and the result of doing this can be seen by clicking here.
This line is the defining geometry line from which the architecture of the gabled roof of the main chamber is constructed. If you zoom in on the main chamber area you can see that if this 1 radian line from the Sun were to be continued it would pass through the apex of the roof gable above the main chamber of the pyramid. At present, there is no way within the geometry to make that connection, but later in this work that will be possible.
The roof stones of the main chamber of the Great Pyramid of Giza are built at an angle of 1 radian to the vertical, and the 1 radian line which emanates from the Sun is clearly intentional and a fundamentally important part of the pyramid's geometry.
