Overview of the IRAM 30 m data for selected lines, one per row. For each transition the panels show a spectrum at the source centre (left), as well as maps of the integrated intensity (moment 0, middle-left, between −87.5 and 2.2 km s⁻¹), intensity-weighted velocity (moment 1, middle-right), and intensity-weighted line FWHM (moment 2, right). The position of the spectrum is indicated on the left-hand panel by a black square. The contours in the three maps indicate the NOEMA 1.4 mm continuum with uniform weighting, as in the right-hand panel of Fig. 2. The beam-size and a scale bar are given in the middle-left panel. For the middle-left and middle-right panels, values are only calculated where the spectrum has a peak intensity above 3σ, with grey used to indicate those regions that do not meet this requirement.
