In the former case the J/psi and a charmed hadron are reconstructed, while the latter process is measured using the recoil mass technique, which allows the identification of two-body final states without reconstruction of one of the charmonia. The measured e+e- -> J/psi ccbar cross section is (0.74 +- 0.08 + 0.09 - 0.08) pb, and the e+e- -> J/psi non-ccbar cross section is (0.43 +- 0.09 +-0.09) pb.
