Notes. This table shows the line parameters of the first ten transitions at HG. Clump, species, and frequency of the corresponding transition are given in the first three columns. For lines with HFS, we give the central frequency of all considered components. The fourth column provides the RMS noise level in the vicinity of the respective transition in mK. The fifth column gives the integrated intensity of the whole line profile, including all possibly occurring components. The remaining columns state the fitted line parameters for the Gaussian and HFS fits: The line intensity Ifit,i(6, 11), the transition LOS velocity with respect to the LSR vi (7, 12), and the FWHM line width ∆vi (8, 13). For Gaussian fits we additionally give the peak temperature of the respective transition Tpeak,i (9, 14), while for the HFS fits we give the optical depth τί obtained by the fit (10, 15). If present, we fitted up to two line-components ì per clump. The columns 11 to 15 are presented in the lower part of the table, after a repetition of clump name, species, and frequency. Values that were not derived or where the transition has not been detected are marked with a minus (-). The full table with all transitions at all clumps is available at the CDS.
