Notes. Here, we describe only those molecules, which show at least three transitions within the covered frequency range. The column densities are given on a main beam brightness line temperature scale, i.e., each column density (exponents are described by round brackets, e.g., 1.4(16) = 1.4 × 1016) is multiplied with the beam filling factor of the corresponding component, to make them comparable to the results given by Schilke et al. (1997), which were indicated here within squared brackets. Additionally, the errors of the fit parameters (indicated by the sub-(left) and superscript (right) values) were determined using the error estimation algorithm included in the MAGIX package.
