a STM image of a 12-atom Ag chain. b SQDM \({V}^{*}\) image of the chain in (a). c Surface potential Φs obtained from deconvolving the \({V}^{*}\) image in (b) using \({\gamma}^{*}\)18. d Comparison of cross sections through the \({V}^{*}\) image (red) and through the used PSF \({\gamma}^{*}\) (black). e Cross section through Φs along the chain in (c) (red dashed). The patterns around the chain are deconvolution artefacts.
