Abstract
Using inclusive decays of , a precise determination of the number of events collected with the BESIII detector was performed. For the two data sets taken in 2009 and 2012, the numbers of events were recalculated to be and , respectively; these numbers are in good agreement with the previous measurements. For the sample taken in 2017–2019, the number of events was determined to be . The total number of events collected with the BESIII detector was determined to be , where the uncertainty is dominated by systematic effects, and the statistical uncertainty is negligible.
