Summary: | BaBar has recently deployed a new event data format referred to as the Mini.
The Mini uses efficient packing and aggressive noise suppression to represent
the average reconstructed BaBar event in under 7 KBytes. The Mini packs
detector information into simple transient data objects, which are then
aggregated into roughly 10 composite persistent objects per event. The Mini
currently uses Objectivity persistence, and it is being ported to use Root
persistence. The Mini contains enough information to support detailed detector
studies, while remaining small and fast enough to be used directly in physics
analysis. Mini output is customizable, allowing users to both truncate
unnecessary content or add content, depending on their needs. The Mini has now
replaced three older formats as the primary output of BaBar event
reconstruction. A reduced form of the Mini will soon replace the physics
analysis format as well, giving BaBar a single, flexible event data format
covering all its needs. |
