We tested a posteriori correction suggested previously for the state-specific multireference Brillouin-Wigner coupled-cluster singles and doubles (MR BW CCSD) theory, to eliminate its size-extensivity error. The correction was applied to a two-reference BW CCSD model by using the cc-pVXY basis sets (X=2,3,4) and it was tested by calculating the spectroscopic constants of the F2 molecule.
