PACS spectral maps in the H₂O 4₂₃−3₁₂ line at 78.74 μm, the OH line at 84.6 μm, and the CO 29−28 line at 90.16 μm for a few sources with bright line emission and centrally peaked continuum. The x-axis range covers −450 to 450 km s^-1 and the y-axis range covers −0.2 to 1.2, with line emission normalized to the emission in the brightest spaxel.
