Figure 6
The relative total standard deviation, σt/a, as a function of sinθ/λ is shown as black dots along with its two components σc/a and σp/a, where the subscripts c and p refer to counting statistics and particle statistics, respectively. At small wavevector transfers the uncertainty of the scale factor a is dominated by particle statistics, whereas at high wavevector transfers the major contributor to the total uncertainty is the counting statistics. |
