Editing ATLAS experiment (section)

====Analysis process====
ATLAS permanently records more than 10 [[Byte#Multiple-byte units|petabyte]]s of data per year.<ref name=fact_sheets/>
Offline [[event reconstruction]] is performed on all permanently stored events, turning the pattern of signals from the detector into physics objects, such as [[Particle jet|jets]], [[photon]]s, and [[lepton]]s. [[Grid computing]] is being used extensively for event reconstruction, allowing the parallel use of university and laboratory computer networks throughout the world for the [[central processing unit|CPU]]-intensive task of reducing large quantities of raw data into a form suitable for physics analysis. 
The [[software]] for these tasks has been under development for many years, and refinements are ongoing, even after data collection has begun.
Individuals and groups within the collaboration are continuously writing their own [[computational physics|code]] to perform further analyses of these objects, searching the patterns of detected particles for particular physical models or hypothetical particles. This activity requires processing 25 [[Byte#Multiple-byte units|petabyte]]s of data every week.<ref name=fact_sheets/>
