Left: $c_{\Delta y}({\rm Acc}\times \varepsilon)$ factors of the selection criteria of the analyses for prompt and non-prompt D mesons as a function of $\pt$. Right: raw fraction of non-prompt $\Dzero$, $\Dplus$, and $\Ds$ mesons in the raw yield as a function of $\pt$. The vertical bars and boxes display the statistical and systematic uncertainties, respectively.
