WISE images towards G304.74 overlaid with contours of SABOCA 350 μm dust continuum emission from Fig. 1. The images are shown with logarithmic scaling to improve the colour contrast. A scale bar of 1 pc projected length is shown in the bottom left corner of each panel. The striation 1 is labelled in the 12 μm image, while striation 2 lies outside the image boundary (cf. Fig. 2).
