Calculated diffractometer arm angle, 2Θ, in degrees for the LaB6 100 peak, d = 4.15689 Å, at 35 keV, 2θ = 4.88410°, as a function of zd, with L = 442.5 mm, L2 = 350 mm, θa = 3.2382° (Si 111 analyzer), for ϑx = 0 (black) and ϑx = 0.5° (red). The analyzer roll results in the maximum of the curve moving to 2Θ = 4.88416° at φ = 0.5002°, with zd = 0.243 mm, and the corresponding za = 0.328 mm, as the roll deflects the beam back towards the center.
