what is the difference between "apparent" azimuth and elevation? and non apparent azimuth and elevation? Is there such a difference and how do I convert between them?

Since your location on a planet can either be in planetcentric lat long coordinates or planetographic lat long coordinates i would think
that would effect your azimuth and elevation locations coordinates for the sun but not sure. Its confusing to me.

thank you.

I am not a specialist in astronomy, but azimuth is the compas angle around the horizon, while elevation is the angle how far the object is above the horizon.

The word 'apparent' I know only for elevation. If your eyepoint is above the ground (which it usually is) than the apparent horizon is slightly deeper than the theoretical tangent to the curvature of Earth. This leads to the apparent elevation being slightly bigger than the theoretical one.
