Super Streams

skimbit_10910.hbk run number = 10910 number of events = 35124

This page shows each of the SKIM1 Superstreams and what skims they contain. The (rough) skim ratios based on one file and running old code is also given as well as which data blocks are written out. (The tables were obtained using Irwin's Superstream calculation page)

Note that actual numbers for skim ratios are dated. They may get updated soon.
