Purity of \kzero candidates as a function of \pt. Black markers represent the selection using the nominal invariant mass range $0.485 M_{\pi\pi} 0.510$ \GeVmass, red markers represent the selection using the loose range $0.480 M_{\pi\pi} 0.515$ \GeVmass, and blue markers represent the selection using the tight range $0.490 M_{\pi\pi} 0.505$ \GeVmass.
