The barrier height article is published in the Journal of Chemical Physics on January 6th, 2022. In this article, we studied PZSIC and LSIC performances on a large barrier height database set (BH76 set). The effects of self-interaction correction were investigated. Significant density-driven errors are found in the BH76 set of reactions, but we found the energy corrections due to SIC are equal to much larger than corrections stemming from densities.
