"Table 4" of "Measurement of three jet distributions in photoproduction at HERA"

DESY-HERA. Measurement of the cross section for the photoproduction of the events containing three jets with a three-jet invariant mass M(3J)& gt;50 GeV. Data come from positron-proton scattering with respective energies 27.5 an d 820 GeV. Jets are found using the KTCLUS finder in the inclusive mode. Jet (3)is the highest energy jet. The second systematic (DSYS) error is due to the uncertainty in the energy scale. The numerical values of figures 3 and 4 come from the hztool routine hz98162.F.
