Notes. The different columns show k-bins, mean value Δ212(k, z) and corresponding 1σ error Δ21, err2(k, z). These are achieved from 140 hours of the NCP field data (see Mertens et al. 2025 for details).
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.
