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.
HEAsoft - A unified release of the FTOOLS and XANADU
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
SAOImage DS9 - Astronomical Imaging and Data Visualization
Application: DS9 supports FITS images and binary tables, multiple
frame buffers, region manipulation, and many scale algorithms and
SkyView-In-A-Jar - Running SkyView
on your own computer.
XANADU - Suite of spectral (xspec), timing (xronos),
and image (ximage)
XSELECT - Multipurpose tool for filtering event files
and generating images, spectra, and light curves. Distributed as
part of the HEASARC package on the
XSTAR - Program for calculating physical conditions and
emission spectra in photoionized gases.

Swift CALDB Data updated (15 Aug 2019)
The Swift SC clock correction file has been updated (CALDB update version 20190813).
PIMMS updated to Version 4.10 (15 Aug 2019)
Version 4.10 contains updates for NICER, suitable for Cycle 2 proposals. Note that the broadband background rate reported by version 4.9/4.9a included background counts below 0.2 keV, where the rate is very high. Version 4.10 restricts brodadband count rates for both source and background to the 0.2-12 keV range. This version also contains the current effective area curves for Athena X-IFU
XSPEC 12.10.1m Patch Released (15 Aug 2019)
This patch updates rdblur, kdblur, kdblur2, kerrconv for considerable speed improvements over previous patches, and removes the outdated relline, relline_lp, relline_lp_ext, relconv, relconv_lp, and relconv_lp_ext models.
XSPEC 12.10.1l Patch Released (08 Aug 2019)
The HDUVERS1 keyword has been updated from '1.1.0' to '1.2.1' since CHANNEL and COUNTS columns can be written in 'J' format in output files generated by the fakeit command.
