Fine-structure line emission in [O I] λ 63.2 µm (top left), [Fe II] λ 26.0 µm (top right), and [S I] λ 25.2 µm (bottom left, with the telluric H2O feature). Two-component Gaussian fits are overlaid as colored lines and all spectra normalized to unity at peak. Bottom right: zoom into the Gaussian fits (blue: [O I] λ 63.2 µm, red: [Fe II] λ 26.0 µm, green: [S I] λ 25.2 µm).
