Notes. The rest wavelength λ₀ (μm) of the transition is indicated. The percentages between brackets give the uncertainty on I_int, 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. Transitions that might cause the line blend are mentioned immediately below the flagged transition. Molecular transitions indicated in red coincide with the wavelength range of the line scans in the OT2 program. These detections are not expected to be affected by blends with molecules other than CO and H₂O. Detections listed in black have to be treated with caution, as they have not been checked for potential blending with other molecules.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
