Figure 4
(a) Values of r edge derivative/r baseline and (b) spread of the Gaussian fit of shot-to-shot differences of values of arrival-timing for various center positions and heights of the ROI with the same data sets as used in Fig. 2. The size of the original image is the same as for Fig. 1(a). In (a), standard deviations for two height conditions are shown for reference. In (b), differences are evaluated for results which are extracted for xcenterROI = 0 and a height of 5 pixels. |
