Figure 4
Fitting results for a series of diffraction images with varying sample-to-detector distance (li), neglecting a correction for the offset of the nominal displacement from actual, which results in varying wavelength (λ) values, shown as blue circles, scale to left. The penetration correction (see §4.1[link]), p, is shown as green triangles, right-hand axis. Standard uncertainties are shown as error bars. At short detector distances, p and λ are highly correlated. The red line is a fit of λ = m/li + b, goodness of fit = 14, where b yields λ extrapolated at infinite distance.
