The following software is supported by the HEASARC. Most of this software
is designed for professional researchers and advanced students for the
analysis of scientific astronomical observations in
FITS format. The 'fv' program is also
suitable for more general use by
amateurs and educators for viewing astronomical image files. These
software packages are to be downloaded to the users machine. Web-based
tools are available on our tools
