I would like to submit an erratum for the article with the title ‘Development of Kinetic Energy Density Functional Using Response Function Defined on the Energy Coordinate’ (Int. J. Quantum Chem. 2022;e26969, https://doi.org/10.1002/qua.26969). The corresponding author of the article is Hideaki Takahashi. The author found an error in producing the graph with the legend ‘OF-DFT’ in Fig. 8 in the article. The error in the graph is attributed to the fact that the atomic response function was spuriously multiplied by 2. We refer the editor to the main text of the erratum in more details. The graph was revised using the amended source code. Fortunately, it was found that the corrected graph was changed favorably as compared to the original one, showing better agreement with the reference calculation.
