Corrigendum to “Spherical aberration correction in a scanning transmission electron microscope using a sculpted thin film” [Ultramicroscopy 189 (2018) 46–53] (Ultramicroscopy (2018) 189 (46–53), (S0304399117305259), (10.1016/j.ultramic.2018.03.016))

The authors regret for the typo in Eq. (1), where C_s was exchanged with the adjacent parenthesis. The correct form of the equation is naturally, [Formula presented] On page 2, the combined spherical aberration coefficient C_{s, eff}(α) is calculated. To compensate the microscope's inherent positive spherical aberration C_s, the sign of the aberration imparted by the thin film corrector, [Formula presented], should be negative. This can either be explicitly stated by setting [Formula presented] throughout the paper, or implicitly by rewriting the combined spherical aberration coefficient with a negative sign, [Formula presented]. In either case, the thin film corrector profile, Eq. (3), should concur with the shape presented in Fig. 3. The correction of these typos has no impact whatsoever on the measurements, analysis, or results presented in the paper. The authors would like to apologise for any inconvenience caused.
