Comment on Quintuple-zeta quality coupled-cluster correlation energies with triple-zeta basis sets by D. P. Tew, W. Klopper, C. Neiss and C. Hattig, Phys. Chem. Chem. Phys., 2007, 9, 1921 [erratum]

After rectifying a small programming error, CCSD(F12) correlation energies are even better than previously reported, particularly for double-zeta basis sets.
