Abstract

We have identified an error in the uncertainties of the fitted column densities of complex organic molecules (Table 5 in the published article). In particular, a few upper or lower uncertainties were underestimated by a factor of 10. A script was used to generate the table from the results of radiative transfer modeling (Section 3.4 in the published article). This script assumed the same order of magnitude for both upper and lower uncertainties, which is true in most cases. In a few cases, for example, the CH3OH column density in L1448 NW, - ´ 2.1+ 10 1.1 0.7 15 cm-2, has different orders of magnitude in its upper and lower uncertainties. Thus, it was erroneously reported as - ´ 2.1+ 10 0.1 0.7 15 cm-2, because the script assumed an order of 1014 for both uncertainties. This error affects neither the conclusions nor the results and figures in the published article, because the error only occurred in the making of this table. A corrected version of Table 5 is provided here. (Table Presented). The authors gratefully thank Shih-Ying Hsu for noticing this error and bringing it to our attention.
