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
HEASARC Software Packages
FITSIO - A subroutine library for reading and writing
files for C and Fortran programmers.
FTOOLS - General
FITS file utility programs and mission-specific data analysis
FV - Interactive editor and viewer for astronomical
data files in FITS format.
Also provides access to Hera.

Hera - Run the FTOOLS and XANADU software on the
Hera servers at the HEASARC, without having to install the
software packages locally.
Maki - Displays fields of view for various instruments on
FITS images. Currently supports the Suzaku XIS & HXD, Chandra
ACIS & HRC, XMM EPIC, and RXTE PCA detectors.
PIMMS - Program to estimate count rates from fluxes or
vice versa, or to estimate count rates in one instrument from those
measured in another.
Profit - GUI tool for visualizing and modeling
