L. Gibb, K. A. Van Brunt, S. D. Brittain, and T. W. RettigThere is an error in the source identification in our KL andM band settings. The results change some quantitative aspects of our re-sults, but do not affect our conclusions. HCN and C2H2 were detected toward the northern component (GV Tau N, or the IRC), ratherthan the southern component (GV Tau S). This does not affect the K band settings for which we were observing GV Tau S as statedin the paper. Since the K band settings were used to determine N(CO) and abundances were calculated relative to CO, this decreasesour calculated abundances by a factor of 2. The values in the following table replace those in Table 2 of the paper. The HCN/CO andC2H2/CO symbols in Figure 6 should also decrease by a factor of 2. Our conclusion that the organics are located close to the hoststar ( IRC rather than GV Tau S) rather than the circumbinary material is unchanged. Our discussion regarding the compositional sim-ilarity to chemical models, comets, and other sources is also unaffected.TABLE 2Column Densities and for MoleculesMoleculeColumn Density(1016 cm2)Abundance Relative to 12CO(%)GV Tau N12CO ........................................ 1180a . . .13CO ........................................ 11 0.93C18O ........................................ 1.4  0.5 0.12HCN ........................................ 3.7  0.3 0.31C2H2 ........................................ 7:3þ0:10:2 0.62CH4.......................................... <2.2 <0.19GV Tau S12CO ........................................ 590  120 . . .13CO ........................................ 5.5 0.93aHCN ........................................ <0.48 <0.08a Assuming 12CO/13CO ratio is the same as for GV Tau S.748The Astrophysical Journal, 686:748, 2008 October 10# 2008.
