Planar approximation of angular distance on sky

Summary

Description
English: Three dimensional reference frame where the angular separation is the angle between the points A and B as seen from the center of the sphere O. The shaded gray area represents a plane (e.g., detector imaging the sky) parallel to the sky centered at right ascension (longitude) and declination (latitude) is the frame of the detector that images the sky.
