sextractor
SEXTRACTOR(1) User Commands SEXTRACTOR(1) NAME
sextractor - extract a source catalog from an astronomical FITS image SYNOPSIS
sextractor image [-c configuration-file] [-parameter1 value1 -parameter2 value2 ...] sextractor image_detect image_measure [-c configuration-file] [-parameter1 value1 -parameter2 value2 ...] sextractor -d DESCRIPTION
SExtractor is a program that builds a catalogue of objects from an astronomical image. Although it is particularly oriented towards reduc- tion of large scale galaxy-survey data, it performs rather well on moderately crowded star fields. On Debian systems, sample SExtractor parameter files are installed to /usr/share/sextractor. Operation modes: -h, --help print this help, then exit -V, --version print version number, then exit -d, --dump dump a default configuration file EXAMPLE
For a minimal sextractor run, without customizing any of the parameters, use sextractor file.fits -c /usr/share/sextractor/default.sex -PARAMETERS_NAME /usr/share AUTHOR
