The integrated line intensities in Table 1 of Van der Wiel et al. (2009, A&A 498, 161) should be modified due to an error in the adopted channel widths: values are reduced by ~20% for C2H, H2CO and SO, reduced by a factor ~5 for C18O and HCN, and increased by ~40% for 13CO. Derived column densities for C2H, H2CO and SO are decreased by ~20%; for C18O it is increased by ~40%. Corrected abundance values of C2H, H2CO and SO are a factor <2 smaller than the originally published values. The values for HCN column densities and abundance are replaced by lower limits. Consequences for the discussion and conclusions are minor. In addition, the southwest arrow in Fig. 1 should be shifted to the southwest by ~10.
