By analyzing large-angle Bhabha scattering events, the integrated luminosity of this data set is determined to be 108.49 +/- 0.02 +/- 0.85 pb(-1), where the first uncertainty is statistical and the second one is systematic. In addition, the center-of-mass energy of the data set is determined with radiative dimuon events to be 2126.55 +/- 0.03 +/- 0.85 MeV, where the first uncertainty is statistical and the second one is systematic.eninfo:eu-repo/semantics/openAccessBhabha scatteringluminosityradiative dimuon eventscenter-of-mass energyArticle2-s2.0-8503296925110.1088/1674-1137/41/11/113001Q2Q2WOS:000414482100001
