AstroImageJ (AIJ) is a cross-platform tool for the analysis of scientific astronomical data. Written in Java, it may be quickly installed to run on Windows, Linux, MacOS, and Chromebook systems using packages provided at its website. A distinguishing feature of AIJ is that it provides access to the image data and to datasets derived from the data, while also offering a versatile image display engine for FITS files and many common image file types. Built on publc domain code for ImageJ, it offers plugin and macro capabilities, and its own astronomical graphical user interface that is a modern versatile replacement for special purpose or legacy image display and analysis software.
