Erratum: The Reaction of Polycyclic Aromatic Hydrocarbon Cations with Hydrogen Atoms: The Astrophysical Implications

In the Letter ``On the Radio-to-X-Ray Light Curves of SN 1998bw and GRB 980425 by K. Iwamoto (ApJ, 512, L47 [1999]), the version of the light curve was not accurate enough and has been replaced by the one presented here. The late-time optical light curve of model CO138 is calculated by extending the exponential decay of the light curve of the same model as presented in K. Iwamoto et al. (Nature, 395, 672 [1998]).
