In [IK1], we have shown the existence of a Chevalley basis for the basic classical Lie superalgebras (Theorem 3.9) and define Lie superalgebras over (Corollary 3.10). However, in the case of , our choice of the Cartan matrix in Appendix A is not appropriate and half integers appear as structure constants given by Theorem 3.9. An appropriate choice of the Cartan matrix of type is given.
