As customary, ccECPs consist of spin-orbit averaged relativistic effective potential (AREP) and effective spin-orbit (SO) terms. For the AREP part, our constructions are carried out within a relativistic coupled-cluster framework while also taking into objective function one-particle characteristics for improved convergence in optimizations.
