GISAXS Slices

In grasing incidend SAXS looking at radial integration doesnt make much sence. In GISAXS you rather want to look at horizontal or vertical sclices. That is horizontal or vertical with respect to the scattering surface.

The SAXSDog tools allow to specify Slices of pixels and allow to look at them at the \(q_y\), \(q_z\) scale as they are used in GISAX analysis.

The slice class implements this functionality very much the same as the radial integration except that the labels of the pixels simply are the integer x coordinate in pixels when we want a slice in x direction and the y coordinate when we want the slice in y direction. Oversampling doesnt make any sense in this scenario but the rest is the same. The only subtile thing is to calulate the \(q_y\) and \(q_z\) scale. Because the dedector coorinatesystem may have the x or the y axis aligned with the scattering suface the Slices allows to chose wether we are in plane or verical to the scattering surface. If you want to get correct \(q_z\) values you must also specify the incident angle \(\alpha_i\), (IncidentAngle).
