Figure 10: The spectra for all the sources in Table 2. They are displayed with 50kms^-1 on either side of the velocity range. Dots indicate the velocity range of each object. The channel width in the display is equal to that of the observations (2.27kms^-1 ). For each spectrum, a `` $\ast$ ", ``x",``+" or ``-" refers to previous detections, see Sect. 5.6. For further details see Sect. 4
