// DESCRIPTION: Contains declaration of class ossimAtbPointSource.
// This object provides the statistics associated with a given point on a
// given image corresponding to a matchpoint. A matchpoint contains a
// collection of these point sources, one for each contributing image.
//
// LIMITATIONS: None.
