摘要：

From December 2019 to June 2021, the BESIII experiment collected approximately 5.85 fb(-1) of data at center-of-mass energies between 4.61 and 4.95 GeV. This is the highest collision energy BEPCII has reached to date. The accumulated e(+)e(-) annihilation data samples are useful for studying charmonium(-like) states and charmed-hadron decays. By adopting a novel method of analyzing the production of Lambda(+)(c)(Lambda) over bar (-)(c)pairs in e(+)e(-) annihilation, the center-of-mass energies are measured with a precision of similar to 0.6 MeV. Integrated luminosities are measured with a precision of better than 1% by analyzing the events of large-angle Bhabha scattering. These measurements provide important inputs to analyses based on these data samples.
