Figure 4
Attitude tuning of an XES spectrometer on 4W1B at BSRF. The main window shows the image acquired from the detector, where the circular pattern can be observed, and its shape needs to be optimized. Also shown are the radial (bottom) and angular (irregular curve in the top left) distributions computed from the image. The ROI and origin used in the computation are shown (and can be modified), respectively, with the rectangle and the crosshair in the top left. |
