I'm currently trying to extract the sun angle (azimuth, elevation) from the physical sky object. (In particular the sphere object inside the gizmo)
I used the general approach via Lat/Lon, Julian Date, leap year, Eclipsis, Sun Declination, equation of time, etc.
While doing that, I realized that the Physical Sky behaves different from what I expected.
My calculations seem to be correct (Decl, EqT are all correct), but there is a slight offset that I'm not able to eliminate.
Is it possible to provide the formulas and/or constants that are used in the calculations for the Physical Sky object?
