Determination of uncertainty in the direct beam from the invariant point (center of precession circle). (a) Simulated SA-ECP of Si showing the pyCHORD precession circle, where the + sign marks the start of precession. Inset zooms-in at the center of the [001] zone axis, showing the center of the precession circle. The direct beam [uvw] orientation was found to deviate by only 0.04° from the nominal [001] zone axis. (b) Normalized XCF overlaid on the simulated SA-ECP for the best-fit crystal orientation determined from pyCHORD analysis of the SA-ECP rotation series.
