Mean (left) and standard deviation (right) of the charged-particle transverse momentum spectra as a function of the charged-particle multiplicity (top) and relative multiplicity $N_{\rm ch} / \langle N_{\rm ch} \rangle$ (middle, bottom) for pp, p-Pb, Xe-Xe and Pb-Pb collisions at various centre-of-mass energies per nucleon pair. The bottom panels show both quantities relative to their multiplicity-inclusive value. Statistical and systematic uncertainties are shown as bars and semi-transparent bands, respectively.
