| Due to the distortions inherent in electron lenses, it is important to calibrate the CBED patterns by comparing an unknown pattern from a known structure with standard diffraction angles. A difference of 10% or more is common at large angles, so that angular measurements taken from CBED patterns may contain such error. Therefore, a correcton table needs to be obtained for particular lens currents.
