The $C_0^0(k^*)$ and $\Re C_1^1(k^*)$ parts of the correlation function for (left) $\rm \uppi^{-}K^{-}$ and (right) $\rm \uppi^{-}K^{+}$ pairs, shown as markers for the 5--10\% centrality, with the corresponding fits calculated using the CorrFit package shown as dashed lines. Only half of the statistics is used, corresponding to one magnetic field (positive field polarity). The statistical and systematic uncertainties are shown as vertical lines and boxes, respectively.
