ARCHANGEL is Unix based package for the surface photometry of
galaxies. While oriented for large angular size systems (i.e.
many pixels), its tools can be applied to any imaging data of
any size. The package core contains routines to perform the
following critical galaxy photometry functions: |
- sky determination
- frame cleaning
- ellipse fitting
- profile fitting
- total and isophotal magnitudes
The goal of the package is provide an automated, assembly-line
type of reduction system for galaxy photometry of space-based or
ground-based imaging data. The procedures outlined in the
documentation are flux independent, thus, these routines can be
used for non-optical data as well as typical imaging
ARCHANGEL has been tested on several current OS's (RedHat Linux,
Ubuntu Linux, Solaris, Mac OS X). A tarball for installation is
available at the download page. The main routines are Python
and FORTRAN based, therefore, a current installation of Python
and a FORTRAN compiler are required.
For users who do not wish to install the package on their own
machine, there is a browser based version of the package (with
fewer features) found at the Client/Server link.
The ARCHANGEL package also contains Python hooks to the PGPLOT
package, an XML processor and network tools which automatically
link to data archives (i.e. NED, HST, 2MASS, etc) to download
images in a non-interactive manner. Future releases will
include links to the reduction of the entire 2MASS catalog and
the RSA catalog.
