Source Extractor for Dummies v5

Source Extractor for Dummies is a user manual for the SEXtractor (Bertin and Arnouts 1996) software package for the detection of astronomical sources in fits-files of fields. It has seen much use as a quick tool and is constantly updated with new features. This fifth installment of the user manual is to catch up with these updates and improve explanations and illustration of SE parameters. The manual was written by a user, not a developer and may be incomplete, inaccurate or clearly copied from the official manual v2.3. In short: more pages, more text, less spelling-errors and don't panic. full pdf at: http://www-int.stsci.edu/~holwerda/se.html
