SExtractor

SExtractor (Source-Extractor) is a program that builds a catalogue of objects from an astronomical image. It is particularly oriented towards reduction of large scale galaxy-survey data, but it also performs well on moderately crowded star fields.

The programme was developed at the IAP Terapix facility, and it's dedicated homepage is at http://terapix.iap.fr/rubrique.php?id_rubrique=91/

Help files: Version 1.0a documentation and Version 2.1.3 documentation in postscript format.

The software is described in an A&AS article.

The latest version of the software is located at Emmanuel Bertin's IAP ftp area
