The formula χ=3μ−3b+5ν in Corollary 2.2 in [Hernández, X., Miret, J., Xambó, S., 2007. Computing the characteristic numbers of the variety of nodal plane cubics in . Journal of Symbolic Computation 42 (1–2), 192–202] should be χ=−9μ−3b+5ν. This mistake does not affect the rest of the paper. We also take the opportunity to supply details of the proof that were only hinted at there.
