Download the HEASOFT Software
Current version 6.26.1 Release Notes
All HEASOFT tasks may now be run remotely using the Hera data analysis service at the HEASARC without having to install the software locally. This provides a quick way to try out the software and is ideal for users who have limited or infrequent need to run the HEASOFT tasks. More intensive users of HEASOFT are still encouraged to install the software locally for best performance. Learn more about using Hera.
A download containing all of the package selections can be around 4 Gb in size when unpacked; the actual size will vary depending on the packages you select and - if you choose a binary distribution - the architecture selected. If large file sizes present problems for your connection, it is possible to download the packages you want separately and unpack the tar files on top of each other afterwards, though you may need to either rename each tar file with a temporary name during the process or unpack each file immediately upon downloading so that one tar file isn't overwritten by the next.
Please use the interface below to download pre-compiled binaries, or
if you wish to select only certain parts of the HEASoft suite for your
source code download. For users who want all of the HEASoft source
code, here are direct links to two tar file options, one of the complete
source code, and one which adds
older Xspec model data files:
$ cd heasoft-6.26/BUILD_DIR $ make $ make install
Please click SUBMIT only once, and be patient while a tar file containing your selections is assembled and retrieved.
