Aperture Photometry Tool (APT) is software with a graphical user interface for computing aperture photometry on astronomical imagery, which is a common research task in astronomy. Image overlays, graphical representations, statistics, models, options and controls for aperture-photometry calculations are brought together into a single package. The software also can be utilized as a FITS-image viewer. APT is executed on desktop and laptop computers, and is free of charge under a license that limits its use to astronomical research and education. The software may be downloaded from its official website, and requires the Java Virtual Machine to be installed on the user's computer.

History

The initial version of APT was released on November 2, 2007. The latest version is APT, v. 2.6.7, released on March 20, 2017. The software was developed by Dr. Russ Laher, a member of the professional staff at the Spitzer Science Center, part of the Infrared Processing and Analysis Center (IPAC) at the California Institute of Technology. A paper on APT was published in July 2012 in the journal Publications of the Astronomy Society of the Pacific.[1] A companion paper[2] compares the performance of APT vs. SExtractor,[3] an established command-line software program for aperture photometry.
