Example showing the distribution of ATLASGAL and WISE point sources on a color composite image from WISE (blue: 3.4 μm; green: 12 μm; red: 22 μm) with the 870 μm contours overlaid from ATLASGAL. Red circles show all the WISE sources within 30′′ of the ATLASGAL sources, and dark blue diamonds indicate the associated ATLASGAL and WISE positions likely hosting embedded sources.Light-blue crosses mark the position of CORNISH sources (Urquhart et al. 2013b), while green circles show the positions of all MMB sources (Urquhart et al. 2013a). Thick red circles show the RMS sources (Urquhart et al., in prep.).
