Rick Field's measurement of the underlying event in leading jet events. If the leading jet of the event is within |η|<2, the event is accepted and ``toward'', ``away'' and ``transverse'' regions are defined in the same way as in the original (2001) CDF underlying event analysis. The leading jet defines the ϕ direction of the toward region. The transverse regions are most sensitive to the underlying event.
