Convergence plot for each core (3p, 3s, 2p, 2s, 1s) CV correlation and the total CV correlation to the transition energy for the four (a) Hf⁴⁵⁺, (b) Ta⁴⁶⁺, (c) W⁴⁷⁺, (d) Au⁵²⁺ions in the SCV model. The dashed lines with down triangles (▽), circles (○), up triangles (△), crosses (+) and stars (★) represent the correlation from 3p, 3s, 2p, 2s, 1s in order, while the solid line with dots (●) are the sum of these CV correlation from the SCV model.
