An isophote is a line or contour on a diagram or image that connects points of equal brightness or intensity. In the context of astronomical imaging and other fields such as photography and remote sensing, isophotes are used to represent the distribution of light intensity across a surface, like that of a galaxy, star, or other celestial objects. In astronomy, isophotes can help in studying the spatial distribution of stars within galaxies, the morphology of galaxies, and the characteristics of nebulae.
