* * Normalized top quark pair double-differential cross section as function of M(ttbar) and y(ttbar) * The data are taken from arXiv:1703.01630, tables 11, 12 (Eur.Phys.J. C77 (2017) no.7, 459) [TOP-14-013] * "Measurement of double-differential cross sections for top quark pair production in pp collisions at sqrt(s) = 8 TeV and impact on parton distribution functions" * Treatment of asymmetric systematic uncertainties by splitting into two sources follows description in Section 8.1 of the paper (Eq. 6) * Following systematic uncertainties are omitted: * 1) model systematics due to PDFs (should not be considered in a PDF analysis) * 2) experimenatal systematics due to b tagging (consist of many negligible individual sources, skipping them does not affect the results) * The last bin will be skipped in the fit ('Flag' column), since this is normalised cross section; the results do not depend on which bin is skipped * This cross section is divided by the bin width of the 2nd variable only * * TECHNICAL COMMENT: below Reaction = 'pp jets APPLGRID' is used as a dummy name to enable theory expression treatment * &Data Name = 'CMS 8TeV ttbar
