7. Fit/COM Results View

This view displays the results generated by the fit/COM process.

The left panel shows a preview of the results. Each of those “preview” thumbnails can be dragged and dropped to one of the scatter plots in the center of the window (in the Maps panel).

After selecting a map to display, points can be selected by clicking on the scatter plot. The results along each Q space axis will then be displayed on the three plots on the right (in the Fit panel).

Gaussian fit results

Fig. 7.1 Gaussian fit results view

Available results are:

  • Area

  • Center position

  • Sigma: Standard deviation

The corresponding legends of the right panel plots are:

  • Blue dashed curve: Integrated intensity on the whole Q space

  • Blue solid curve: Integrated intensity in the Q space ROI (only when a ROI is set)

  • Dark dashed curve: Background (only if background is used)

  • Red solid curve: Fitted gaussian (+ background)

Centroid/Max results

Fig. 7.2 Center-of-mass/Max results view

Available results are:

  • COM: Center of mass

  • I_max: Maximum intensity

  • I_sum: Integrated intensity

  • Pos_max: Position of maximum

The corresponding legends of the right panel plots are:

  • Blue dashed curve: Integrated intensity on the whole Q space

  • Blue solid curve: Integrated intensity in the Q space ROI (only when a ROI is set)

  • Dark dashed curve: Background (only if background is used)

  • Vertical black line: centroid position

  • Vertical gray line: maximum position
