Center to Limb Variations (CLV) or limb darkening allow us to characterize different layers of the solar atmosphere. It is possible to use different wavelengths. These variations give information about the quality of the images observed from ground-based observatories that continuously observe the Sun. Also, a brief description of how the Center to Limb Variations can help to describe the stellar atmospheres, specifically in eclipsing binary stars and stars with exoplanets.
