Notes. The horizontal line near ~300 μm shows the transition between the SPIRE SLW and SSW detector arrays (beams between 42′′ and 17′′). The line near ~200 μm marks the lines detected with PACS (spaxel size ~9.4′′). Lines in the PACS ranges with detector leakage are not tabulated. Flux errors up to ~30%. Both the o-H2O 101 and p-H2O 000 ground-state levels are at Elow/k = 0 K.
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.
