Spectra of individual counter images as assembled from clouds identified with Clumpfind, as labeled in Fig. 1. Images #1.2 and #1.3 are blended and identified as a single clump by Clumpfind. The dark blue and red lines show fits with Gaussian functions to the total line profile of each image system shown in Fig. 2, scaled to the total flux in each image. The mismatch between the blue component in image #1.4 can be explained with partial overlap with image #2.2.
