Abstract
Aims. A small error was recently found in the program used to compute the integrated intensities in the article Belloche et al. (2008, A&A, 482, 179).
Methods. We provide new versions of Fig. 2 and Tables 3, 5, and 7 with the correct integrated intensities.
Results. The conclusions drawn by Belloche et al. (2008) are not significantly affected by these corrections. Only the mass, density, and central H₂ column density of the compact source emitting the amino acetonitrile lines appear to have been underestimated by 30–40%. This led to an overestimate of the abundance of amino acetonitrile by the same amount. However, the magnitude of this correction is less than the estimated uncertainties on these parameters.
