Measuring and mapping octahedral tilts with DPC. a The O-coordination of a Sc atom in DSO. b Azimuthal angle of octahedral tilt (polar angle not measured). c In-plane O atomic columns of the Sc octahedral found by identifying the local maxima near the Dy-doublet sites. d The azimuthal angle measured by taking isoline contours of the atomic potential from around each Sc site and identifying the long-axis of the elongated annulus. e Mapped Sc octahedrals where the color corresponds to the azimuthal angle of the octahedral tilt, demonstrating high accuracy of the measurements via STEM-DPC
