Abstract

A package of programs is presented which is devoted to automatic processing of astronomical images,with special reference to the analysis of clusters of galaxies. Problems involved in processing large-size images (e.g. 4000x4000 pixels or more), containing a very large number of objects (several thousands), are such that interactive processing is not practicable and algorithms for automatic threatement must be developed. The package described has a structure centered on two data sets: the 'image data-file' and the 'catalogue'. Details in data organization and handling are exposed together with the I/O management which was adopted. The main automatic processing algorithms are then exposed and some example of threatement are presented. Astronomical results obtained using this software are described in another paper from this same Congress.
