FIG. 14.

$P_{\mathit{ion}}\left(q\right)$ (left) and $P_{\mathit{DNA}-\mathit{ion}}\left(q\right)$ (right) comparison between two analysis schemes for the DNA SAXS data: Black circles are from Meisburger et al.;²⁰ red circles from the method proposed here. Error bars are computed by propagating the errors from experimental intensity data. P(q) is actually a normalized $F_{\mathit{ion}}\left(q\right)F_{\mathit{DNA}}\left(q\right)$ curve (in Fig. 8), so the error bars here are the same error bars in Fig. 8 after normalization. They were computed by propagating the error bars when (square root) subtracting the two experimental intensities I_off and I_on for ${\tilde{F}}_{\mathit{ion}}$, times with ${\tilde{F}}_{\mathit{DNA}}$.
