17. Skims¶

The skim package is a collection of high-level analysis scripts that reduce the data set to a manageable size by applying a simple selection. The input to a skim are MDST files of processed data. The output is a so-called uDST (micro-DST) which actually contains more information but fewer events. That is, a uDST file contains the same as an MDST but with the addition of ParticleList objects of candidates build using the modularAnalysis tools.

To get information about existing skim, ask the current skim group liaison.
