Summary
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. Its main features are:
Simplicity of usage and configuration. ffl Speed: typically 500
kpixel/s with a Pentium2@450MHz.
Ability to work with very large images (up to 65k pixels on 32bit
machines, or 2G pixels on 64bit machines), thanks to buffered image
access.
Robust deblending of overlapping extended objects.
Real-time filtering of images to improve detectability.
Neural-Network-based star/galaxy classifier.
Flexible catalogue output of desired parameters only.
Pixel-to-pixel photometry in dual-image mode.
Handling of weight-maps and flag-maps.
Optimum handling of images with variable S/N.
Special mode for photographic scans.
Modularity of the code that enables one to implement new
parameters.
