where E SS/OS-MP2 C are the same and opposite spin correlation energies at the MP2 level, and c C the scale parameter for the DFT correlation, which is now uncoupled from the MP2 contributions, as is common for other ground-state SCS/SOS-DHDFs. The correct values for the MP2 scale parameters to be used in our assessed functionals are shown in Tab. 1. The current ORCA5 versions would not give the correct ground-state energies and the Supporting Information (SI) provides examples input files to change the ground-state energy expression. We intend to implement the correct ground-state expressions for future ORCA releases, so that the simple functional keywords calculated the correct ground-state energies.
