Accurate centrality determination is essential for comparing experimental data obtained from different experiments and for benchmarking against theoretical models. This work presents a modification of the approach for centrality determination using charged particle multiplicity based on Bayes' theorem. The proposed improvements enable an estimation of event registration efficiency as a function of the impact parameter.
