Color RGB images for NGC 625 (left panel), NGC 1705 (middle), and NGC 5253 (right) with Herschel/PACS-R as red, ACA ¹²CO(1–0) as green, and HI as blue; North is up, East is to the left. The image dimensions are 130 × 105 arcsec² for NGC 625, NGC 1705, and 120 × 105 arcsec² for NGC 5253. All observations have roughly spatial resolutions of ∼250 pc (see text for more details). The white color indicates where HI, CO, and dust are cospatial. As in Fig. 2, also indicated are the HII regions A–D of NGC 625 (Cannon et al. 2004); the dust clouds and SSC in NGC 1705 (Cannon et al. 2006); and the unusual CO+dust cloud “D1” in NGC 5253 that coincides with the brightest, highly dust embedded SSC (Turner et al. 2017).
