Comparing mpfit with single peak fitting on experimental data. a Experimental \({\text {LiNbO}}_{3}\) BF-STEM data with the red points referring to the intensity minima, green points referring to the fitted positions as calculated by the single peak approach, and yellow points being the points as calculated by the mpfit approach. b Intensity profile of the image along the white arrow, with the red arrows corresponding to intensity minima, green arrows to single peak refinement results, and yellow arrows referring to the mpfit refinement results
