Figure 8
PDF data of an in situ brushite sample, modeled against a published brushite structure. The fit was determined by calculating a theoretical PDF from the published structure, allowing for some parameter refinement, and comparing it with the observed PDF data. The difference between the observed and the fitted data is random and mostly oscillates near zero. At low r (x axis), where the signal contains artifacts of the Fourier transform, the errors in peak positions and intensities are high. |
