Conceptual steps of the slicing algorithm for energy calibration. Panel (a) shows an example elastic scattering image. The rectangular bars represent the ROIs used in the projection and fitting. A Gaussian fitting is employed to extract the peak position of the pixels (b), ROI 1 is used as an example of projection. In batch fitting, the initial parameters of peak position are prepared by using a peak-finding function from the filtered image. This allows the ROI to be selected as narrowly as possible, despite the pronounced noise level. (c) Representative pixel–energy relation for different ROIs along the non-bent axis. The colors correspond to the ROIs used in panel (a). |
