Skimming REST Data Challenge Data
- I have created a factory for skimming data into different output REST files. It will be available soon.
- Below are some statistics on the data challenge data for various potential topologies/skims.
- Data challenge data-set size: ~5 billion events, 50k events per file: ~100k files, ~100 MB per file: 10 TB total.

- Note: For a charged particle to be valid, it must have 45.0 < Vertex-Z < 85.0.
- Note: π0 means: 0.1 < γγ Invariant Mass < 0.17 (Loose Cut).
