Figure 2
After loading the data files, a first map of the intensity (Fig. 1[link]b) is automatically displayed and the main menu appears (a). From it one may modify the intensity map or go to the filter selection. The filter menu is shown in (b). Several geometries are available: horizontal, vertical or oblique rectangles, with display versus the X and Y axis, or the wavevector, respectively, or sectors with display versus the radius, ρ, or rings versus the angle, θ. For the fit procedure it is possible to define the fit characteristics (dimension number, iteration number, information level etc.) from a general menu (c). Model functions, centred or not centred on the main beam, may be chosen from a submenu (d).
