System size dependence of particle-ratio fluctuations in Pb+Pb collisions at 158$A$ GeV

New measurements by the NA49 experiment of the centrality dependence of event-by-event fluctuations of the particle yield ratios (K$^{+}$+K$^{-}$)/($\pi^{+}+\pi^{-}$), (p+$\bar{\text p}$)/($\pi^{+}+\pi^{-}$), and (K$^{+}$+K$^{-}$)/(p+$\bar{\text p}$) are presented for Pb+Pb collisions at 158$A$ GeV....
