The new ATLAS Open Data website

Changing is always tough, but sometimes necessary. We noticed that we had too many resources scattered around, and too little information about where is what. Below you will find a detailed breakdown of all the resources we have, where they were, and where they are now.

Feedback and suggestions are much appreciated, so if something is missing or could be done better, please get in touch!

Known issues

Lost 8 TeV samples

Please follow the updates at MYATLAS-113.

Jupyter Notebooks have some deprecated code

Please follow the updates at MYATLAS-114.


Introduction of Public Likelihoods documentation and 13 TeV docs update.

  • A new tool for exploring statistical workspaces is now present at the public likelihoods page.
  • Update to the 13 TeV documentation:
    • General reorganisation of the content.
    • Introduction of the live dataset navigator (to be upgraded).
    • Fix broken links and minor revisions.

See merge requests !12 and !13.


Major spring cleaning and upgrades.

  • Upgrade of the Docusaurus framework to v3: this fixes a number of bugs, e.g. table of content sidebars stuck in the middle of the page.
  • General re-organisation of content and website structure aimed to:
    • Improve the clarity of the resources that we provide.
    • Improve the website's navigability through category cards.
    • Fix broken links and redirection of old resources to the new domains.
  • Introduction of the Open Data for research release.

See merge request !10.
