skimming
n.— «The last step in processing is the separation of data into different streams based on the event types apparent in each collision. This process, called skimming, was performed at the computing centers—SLAC, GridKa in Germany, and RAL and the University of Manchester in the U.K. By upgrading the efficiency of the data skimming system, researchers hastened along this time-intensive process.» —“BaBar Collaboration Completes Data Reprocessing” by Kelen Tuttle PhysOrg.com Dec. 18, 2008.
