Future developments

Further enhancements may be necessary in the light of in-flight experience, eg.

• location of the source within the camera field-of-view, to avoid CCD boundaries)
• the nearest-neighbour distance threshold may need to be a function of source brightness, to alleviate problems with multiple detection of bright sources (this depends on the performance of the source detection software)
