What to Bring

Each attendee is requested to bring a personal laptop.

WiFi: wireless access is provided via the RAS wifi network

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). 

ESA Gaia Archive

If you don't alread have an account on the ESA Gaia archive, then please register for one. 

Installing the 'helper' clients.

Java is required by Topcat and Aladin: any recent java version is OK, but Oracle/Hotspot Java SE (from https://www.oracle.com/java/technologies/) 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:   https://www.anaconda.com/products/individual   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

During the breakout sessions, the tutors and attendees will aim to work through a number of the use cases that attendees have suggested at the time of registration. In addition, attendees can work through cases that they suggest on the day, with help from the tutors.  

Attendees and tutors are encouraged to keep a running log (please edit this Google Doc  of what they work on during the breakout sessions. This will be a public document, hence will be shared with however discovers this link.
