7.3.4 Spectral Profile Plotting

From the Main Toolbar (see Fig. 7.3), the Spectral Profile plotting tool can be selected. This creates a new Spectral Profile window containing an x-y plot of the intensity versus spectral axis. The displayed spectrum is extracted in region marked with the Point, Rectangle, Ellipse or Polygon Region tool in the Viewer Display Panel, where the values for extended regions are computed as the mean over all pixels within the marked region. For Point positions, it is possible to mark multiple positions position and switch between the positions by hovering over the respective markers (to remove points, hover over and hit ESC). The spectrum shown in the Spectral Profile window (right panel in Figure 7.12) is automatically updated if the corresponding region is dragged across the image in the Viewer Display Panel (right panel in Fig. 7.12).

Figure 7.12: The Spectral Profile panel (right) that appears when pressing the button Open the Spectrum Profiler in the Main Toolbar and then use the tools to select a region in the image, such as the rectangular region on the left panel. The profile changes to track movements of the region if moved by dragging with the mouse.
