Normalized absorption notch profiles N(y, Θ) and notch parameters as a function of angular deviation Θ from exact Bragg backscattering of probe C440. (a) An example of the normalized absorption notch profile N(y, Θ) = S(y, Θ)/S(y, Θ∞): that is, the ratio of the X-ray beam spectral image profile S(y, Θ) [see Fig. 4[link](b)] to the X-ray beam image profile S(y, Θ∞) when unaffected by the absorption notch [see Fig. 4[link](a)]. (b) Absorption notch location yn. (c) Notch FWHM Δyn. (d) Absorption effect 1 − N(yn, Θ).
