Fermilab Tevatron. Measurement of the inclusive jet cross section in PBAR P collisions at a centre-of mass energy of 1.96 TeV from a data sample of integrated luminosity of 0.70 fb-1. Data cover the jet tansverse momenta fom 50 to 600 GeV and jet rapidities from -2.4 to 2.4. In addition to the cross section values with statistical and overall systematic uncertainties, this record also contains details of the various sources of systematic uncertainties and their correlations. The data are taken from the D0 web site www-d0.fnal.gov.
