Δ(2θ) calculated from equation (2.2.2)[link] for a beamline with a double-crystal Si(111) monochromator, an Si(111) analyser (Δm = Δa and θm = θa) and an FWHM vertical divergence of 25 µrad at λ = 0.4 Å (solid line: Δm ≃ 8.3 µrad, θm = 3.6571°), λ = 0.8 Å (dashed line: Δm ≃ 16.6 µrad, θm = 7.3292°) and λ = 1.2 Å (dotted line: Δm ≃ 25.2 µrad, θm = 11.0319°).
