18. This paper has a misprint in Eq. (15) (the sign of the first term in curly brackets should be negative), with the remaining equations being correct. The electromagnetic square radius of the pion quoted in the paper is incorrect; the correct value is rπ2 EM=0.46fm2, in much better agreement with data than naive (single ρ) VMD.
