The variation in s causes intensity oscillation across the disk. For instance, the intensity of a diffracted beam, I_{g}(s), is the function of an effective deviation parameter, s_{eff}:  [1990a] where ξ_{g} is the extinction distance for the diffraction g. s_{eff} is given by, Figure 1990 shows the calculated intensity profile of I_{g} as a function of s and 2θ_{B} (the separation of the (000) and (hkl)disks). The profile in Figure 1990 (a) is also called rocking curve.
