An error was discovered in Figures and and they should be replaced by the figures below. The figure captions should remain unchanged. The sentence in Section 3.2 ‘Even though a smaller part of the system is correlated in ECC2 than in MP2 and CC2, the ECC2 energy is closer to the CCSD values.’ should be removed. The conclusions remain unchanged.
