ImageJ is a graphical user interface (GUI) driven, public domain,
|
|
Java-based, software package for general image processing
|
|
traditionally used mainly in life sciences fields. The image processing
|
|
capabilities of ImageJ are useful and extendable to other scientific
|
|
fields. Here we present AstroImageJ (AIJ), which provides an astronomy
|
|
specific image display environment and tools for astronomy specific
|
|
image calibration and data reduction. Although AIJ maintains the
|
|
general purpose image processing capabilities of ImageJ, AIJ is
|
|
streamlined for time-series differential photometry, light curve
|
|
detrending and fitting, and light curve plotting, especially for
|
|
applications requiring ultra-precise light curves (e.g., exoplanet
|
|
transits). AIJ reads and
|
|
writes standard FITS files, as well as other common image formats,
|
|
provides FITS header viewing and editing, and is World Coordinate
|
|
System (WCS) aware, including an automated interface to the
|
|
astrometry.net web portal for plate solving images. AIJ provides
|
|
research grade image calibration and analysis tools with a GUI driven
|
|
approach, and easily installed cross-platform compatibility. It
|
|
enables new users, even at the level of undergraduate student, high
|
|
school student, or amateur astronomer, to quickly start processing,
|
|
modeling, and plotting astronomical image data with one tightly
|
|
integrated software package.
|
|
|
|
Rather than building from source, this package just copies a binary
|
|
into the system. It is recommended that post-installation, the user
|
|
changes the permissions of the install directory so that the user can
|
|
update the software:
|
|
|
|
# chown -R myname.users /usr/lib64/AstroImageJ
|
|
|
|
It is further recommend to update to the latest daily build - in
|
|
particular, the WCS-finding routine is broken on earlier versions.
