Reconstruction

Fragmented data from various sub-detectors are processed or “reconstructed” to provide coherent information about individual physics objects such as electrons or particle jets. Reconstruction involves putting together information from different sub-detectors into a coherent representation of every particle collision. However, the format for the first tier of reconstructed data is often too huge for meaningful analysis, and is converted into a lighter format, such as the AOD format for CMS.
