DESCRIPTION

       SExtractor  is  a  program  that builds a catalogue of objects from an astronomical image.
       Although it is particularly oriented towards reduction 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
