SPIRE-350 map of NGC 300 overplotted with the final catalogue of 146 GDCs (small black dashed ellipses) and the APEX CO(J = 2-1) pointed observations from F14 (remaining small circles; the colours indicate whether there was a detection (blue), marginal detection (yellow), or non-detection (red) in CO(J = 2-1)). The beam size of the Herschel image is indicated in the box in the lower left of the image. The white contour lines trace flux values of 0.04 Jy. The large black dashed ellipse indicates the isophotal radius R₂₅ as defined in Table 1.
