Abstract
A simple analytic formula for the three-dimensional light distribution in spherical galaxies is given that fits measured brightnesses as well as, or better than, existing models. It has the advantage that many desired quantities, such as surface brightness, gravitational potential and projected velocity dispersion can be easily computed.
