Testing deblended 850 μm flux densities using A3COSMOS. Top left: comparison between deblended 850 μm flux and ALMA 870 μm photometry from the blind ALMA catalogue (red: XID+ deblended fluxes; blue: super-deblended fluxes from Jin et al. 2018). The blue vertical dotted line corresponds to the rms noise level of S2CLS-COSMOS. Top right: similar to the top left panel but for comparison with the ALMA prior photometry measurements. Bottom left: normalised distributions of flux difference (between deblended fluxes and ALMA blind photometry) divided by the 1σ flux uncertainty, for sources with ALMA measured fluxes >4 mJy. The vertical dotted line corresponds to no difference between the deblended flux and the ALMA flux. Bottom right: similar to the bottom left panel but for comparison with the ALMA prior photometry catalogue.

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.
