Integrated HIFI intensity map of the p-H₂O 2₀₂-1₁₁ line ([−50,−38 ] km s^-1) toward the IRDC region (color image). The black contours show the SABOCA continuum emission at 350 μm from 5% of the peak flux in steps of 10%. The triangles mark the positions of the submillimeter continuum peaks reported in Table 3. Beams of the observations of the p-H₂O 2₀₂-1₁₁ line (white circle) and of the 350 μm continuum (red circle) are shown in the bottom left corner.
