Visualisation tools¶
During the course we will introduce several tools that are useful to visualise and explore astronomical data. Those tools cannot be run in the web-based system of your JupyterHub environment. Fortunately, the main tools we will use are available for a variety of platforms and operating systems and you should be able to use them in your local machine without major installation issues.
