FTOOLS is a collection of utility programs used to create, examine, or modify the contents of FITS data files. There are also user friendly GUI tools which allow interactive browsing of FITS files and provide a more intuitive interface for running the FTOOLS. The FTOOLS package forms the core of the HEASARC software system for reducing and analyzing data in the FITS format.
Each FTOOLS task is a separate program that performs a single simple operation. The FTOOLS are primarily a Unix based package, although a Windows version was created for version 4.2 (a 5.0 version is in the works). Most of the powerful GUI interfaces run only on Unix, although the core GUI tool, fv, is available for Unix, Windows, and MacOS. Further discussion of supported platforms is available in the FTOOLS FAQ. Scripts are available for combining several FTOOLS to perform complex tasks. All of the core FTOOLS programs share several common design features:
These design decisions have resulted in a software package that is exceptionally portable and can be integrated into new environments with a minimum of modification to the source code.
