Notes. HST and MIRI fluxes measured through aperture photometry (see Sect. 3.2). Photometric values beyond 2 μm correspond to the GOODS-N catalogue presented in Liu et al. (2018). Upper limits are set as 3σ values in those filters where the uncertainty is larger than the flux measurement. Hyphens represent the non-coverage of the object by the corresponding filter. † Redshift assumed during the SED fitting, computed in Tan et al. (2014). †† Redshift derived in Daddi et al. (2009).
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.
Initial download of the metrics may take a while.
