Compilation of the continuum data from 70 μm to 1.2 mm wavelength as labeled in each panel. The top-row presents the data on a smaller spatial scale as marked in the bottom-left panel. The color-scale is chosen in each image individually to highlight the most important features. Contour levels of the 870 μm data start at the 3σ levels of 0.27 mJy beam^-1 and continue in in 3σ steps to 2.7 Jy beam^-1, from where they continue in 2.7 Jy beam^-1 steps. The 1.2 mm data are contoured in 3σ levels of 30 mJy beam^-1. The numbers in the top-left panel label the sub-cores, the white small box there marks the region shown in Fig. 5, and a scale-bar for a distance of 5.5 kpc is shown as well. The crosses in the bottom-left panel mark the positions of a double-component radio recombination line Hii region from Anderson et al. (2011), the W43-MM1 position from Motte et al. (2003) as well as the approximate center of the Wolf-Rayet/OB cluster (Blum et al. 1999; Motte et al. 2003).
