Installing the 'helper' clients:

Topcat (recent version, preferably v4.6+): see
Aladin (recent version, preferably v9+): see
Java is required by Topcat and Aladin: any recent java version is OK, but Oracle/Hotspot Java SE (from is recommended rather than OpenJDK.  On linux you can run “java -version” to see which you have.

Instructions for installing Python

If you don’t already have a Python (scientific) stack on your computer, you can easily install the Anaconda stack. This comes with “batteries included”, and comes packed with numpy (numerical python), scipy (scientific python), Astropy (astronomical Python library), and matplotlib (a plotting library).

You can get the Python 2.7 or Python 3.5 Anaconda version from:

If you don’t know which Python version to chose, then select Python 3.5 (graphical or command line installer -- either is OK).
