A procedure to determine the centrality of collisions with the LHCb detector is implemented for lead-lead collisions root s(NN) = 5 TeV and lead-neon fixed-target collisions at root s(NN) = 69 GeV. The energy deposits in the electromagnetic calorimeter are used to determine and define the centrality classes. The correspondence between the number of participants and the centrality for the lead-lead collisions is in good agreement with the correspondence found in other experiments, and the centrality measurements for the lead-neon collisions presented here are performed for the first time in fixed-target collisions at the LHC. %K Pattern recognition %K cluster finding %K calibration and fitting methods %K Performance of High Energy Physics Detectors %K Simulation methods and programs %R 10.1088/1748-0221/17/05/P05009 %U https://arxiv.org/abs/2111.01607 %U https://doi.org/10.1088/1748-0221/17/05/P05009 %P P05009 - 31pp
