What to Bring

Each attendee is requested to bring a personal laptop.

WiFi: wireless access is provided via eduroam (preferred) but if you do not have an eduroam account please contact Nigel Hambly beforehand to arrange personal visitor network access credentials for the day.

Pre-Meeting Software

All attendees will get the chance to use the Gaia archive tools in the afternoon sessions. Please aim to install the following software (if you don't already have them). 

Installing the 'helper' clients.

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

Some scripting access will be provided using 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).  

Background Material and Breakout Sessions
