Short summary
The term mascon either refers to the fact of a significant gravity anomaly within a celestial body or to a modelling of these gravitational anomalies by localising base functions. The localising base functions that are labelled as mascons include point masses or surface elements based on the simple layer representation. In the case of surface elements, the surface density is constant per mascon, and each localising base function is a two-dimensional step function on the sphere.
