In this analysis the behavior of the underlying event in hard scattering proton-antiproton collisions at 300 GeV, 900 GeV, and 1.96 TeV is studied. The 300 GeV and 900 GeV data are a result of the Tevatron Energy Scan which was performed just before the Tevatron was shut down. The energy ratio histograms can be created from different runs with a merging script available in the Rivet bin directory. Beam energy must be specified (in GeV) as analysis option "ENERGY" when rivet-merging samples.
