Left panel: spectroscopic versus photometric redshifts for the 60 cluster fields in this study. Outliers, objects for which , are marked in red. The outlier fraction is less than 3%, the scatter (in ) of the remaining objects is σz = 0.035. Right panel: same for the COSMOS field, also using only the ugri-filters. The outlier fraction and scatter are slightly larger as a result of deeper spectroscopic data (in particular at higher redshift where the ugri-filters lose their constraining power).

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.
