ATLAS proANUBIS calibration data set<p>The ANUBIS prototype 'proANUBIS' collected data on the scaffolding of the A side of the ATLAS cavern during 2024 and 2025 pp data-taking. To assist with calibrating and measuring the performance of the proANUBIS tracking and timing for particles visible in both ATLAS and proANUBIS, this ATLAS open dataset contains events with muons or jets that have trajectories consistent with reaching proANUB
