ATV is a
program for display and analysis of astronomical images using the
IDL image-processing language. It allows interactive control
of the image scaling, color table, color stretch, and zoom, with
support for world coordinate systems. It also does
point-and-click aperture photometry, simple spectral extractions,
and can produce publication-quality postscript output
An interactive display tool
for astronomical images written in IDL.
Instructions for using ATV
ATV requires IDL version 8.0 or
higher, and the libraries listed below. It is particularly
important to have up-to-date versions of the GSFC IDL astronomy
user's library and the Coyote library, since there have been very
substantial changes to the GSFC library and its dependence on
Coyote routines during the past few years.
To run ATV, you will need:
Note about other
versions of ATV:
There are a few alternate and forked versions of ATV that can be
found on other sites, some of them modified to add features
specific to certain telescopes or instruments. These include
a version designed for reduction of Spitzer IRS data (as part of
the SMART package), the PhAst
program which includes added astrometry and photometry
functionality, and a very old version of ATV with added HEALPIX
support that's distributed as part of the idlutils
package. However: I take no responsibility for any
forked versions of ATV, and the instructions and information on
this site may not apply to any modified ATV versions that you find
elsewhere. If you're using the idlutils distribution
but don't need to use the HEALPIX support, then I recommend that
you delete the ATV version that came with idlutils, and install
the current version of ATV instead.
