Precession series analysis linking SA-ECP intensity and BSE contrast. (a) Schematic representation of the precession setup: the sample normal Mathematical equation is tilted by σ = 7° relative to the incoming beam direction Mathematical equation, and precession is performed by rotating around Mathematical equation, sweeping through ω = 0–360° while acquiring SA-ECPs and BSE images. (b) Comparison of intensity profiles extracted from the experimental SA-ECP series, dynamical simulations, BSE image series, pyCHORD orientation search and GA-based fit, all plotted against precession angle. (c) Polar map visualization of precession intensity centered around the reference SA-ECP, highlighting the angular relationship between Kikuchi band positions (color coded) and intensity modulations around the precession circle.
