Comparison of the fractions of prompt $\Dplus$- and $\Ds$-meson raw yields as a function of $\pt$ between the FONLL-based and the data-driven approach. The results from the data-driven method are shown as diamond markers with the error bars (boxes) representing the statistical (systematic) uncertainty. The central values of $\fprompt$ from the FONLL-based approach are shown by the continuous line and their uncertainty by the shaded boxes.
