Reconstructed (raw) yields of $\Kzs$ (open circles), $\mathrm {\Lambda}$ (open squares)and $\mathrm {\overline{\Lambda}}$ (open triangles) as a function of $\pT$. The change of bin size results in successive offsets of the raw counts at $\pT = [1.4, 1.6, 2.4]  $GeV/c for $\Kzs$ and$\pT = [1.6, 2.4, 3.0] $GeV/c for $\mathrm {\Lambda}$ and $\mathrm {\overline{\Lambda}}$ Uncertainties correspond to the statistics and the systematics from the signal extraction They are represented by the vertical error bars. The horizontal error bars give the bin width.
