Although it is particularly oriented towards reduction of large scale galaxy-survey data, it performs rather well on moderately crowded star fields. .RE On Debian systems, sample SExtractor parameter files are installed to /usr/share/sextractor. .RE .SS "Operation modes:" .TP \fB\-h\fR, \fB\-\-help\fR print this help, then exit .TP \fB\-V\fR, \fB\-\-version\fR print version number, then exit .TP \fB\-d\fR, \fB\-\-dump\fR dump a default configuration file .SH EXAMPLE For a minimal sextractor run, without customizing any of the parameters, use \fBsextractor file.fits \-c /usr/share/sextractor/default.sex \-PARAMETERS_NAME /usr/share .SH AUTHOR Written by Emmanuel Bertin (Institut d'Astrophysique de Paris and Observatoire de Paris). .PP Copyright 1994-2005 Emmanuel Bertin .RE This is free software; see the source for copying conditions.
