Figure 3
Example demonstrating the possibility of negative CC1/2 when rejecting reflections with negative intensities from a data set. The plots show ∊1 versus ∊2 for simulated data having Gaussian noise and no signal (τ = 0). (a) 1000 unique reflections, each represented by two observations; no rejections. The correlation of ∊1 and ∊2 is near zero. (b) From the 1000 unique reflections, those with negative intensity (∊1 + ∊2 < 0) were rejected. The resulting correlation between ∊1 and ∊2 is about −0.47. (c) From the 1000 unique reflections, those with negative ∊1 or negative ∊2 were rejected, also resulting in positive (merged) intensity. The resulting correlation between ∊1 and ∊2 is near zero. |
