SAO ds9226 is not a requirement of
Gnuastro, it is a FITS image viewer. So to check your inputs and
outputs, it is one of the best options. Like the other packages, it
might already be available in your distribution’s repositories. It is
already pre-compiled in the download section of its web page. Once you
download it you can unpack and install (move it to a system recognized
directory) with the following commands (x.x.x
is the version
number):
$ tar xf ds9.linux64.x.x.x.tar.gz $ sudo mv ds9 /usr/local/bin
Once you run it, there might be a complaint about the Xss library,
which you can find in your distribution package management system. You
might also get an XPA
related error. In this case, you have
to add the following line to your ~/.bashrc and
~/.profile file (you will have to log out and back in again for
the latter):
export XPA_METHOD=local
