Notes. The approximate central wavelength λ0 (μm) of the emission line is indicated. The percentages between brackets give the uncertainty on Iint, which includes both the fitting uncertainty and the PACS absolute-flux calibration uncertainty of 20%. Line strengths indicated with are flagged for potential line blends.
