ALMA 1.3 mm continuum images of the six targeted regions in Sh2-284. The blue color scale and blue contours show the ALMA continuum emission, with contour levels of (4, 8, 16, 32, 64) × σ, where σ is the rms sensitivity of each field listed in Table 1. Gray contours show the Herschel 500 μm emission at (30, 60, 90, 120, 150, 180) MJy sr⁻¹, tracing the larger-scale cloud structure. The green dashed boxes indicate the regions shown in Figure 3. All panels are displayed with the same physical scale; the scale bar and color bar are shared by all panels.
