Figure 6
Determination of detector parameters. Shown is the optimization error versus the eight considered parameters: the center channels of the detector and the width of the pixels in both directions, the detector tilt (azimuth and tilt angle), the detector rotation, and the offset of the outer goniometer stage. The found optimum is marked by a black circle. All other points correspond to fits that did not reach the global minimum; these were produced from various different starting parameters of the fit. Green lines are guides to the eye to visualize the minimum found in all the parameters. The points of the fits are colored to enable the identification of correlations. |
