Notes. Compilation of visually identified features deviating from a pure disc emission, including blue-shifted absorptions (blue-abs), red-shifted absorptions (red-abs), broad absorptions (broad-abs), flat top profiles (flat-top), skewed emission profiles (skewed), P Cygni-like (P-Cyg) inverse P Cygni-like (iP-Cyg), broad emission wings (broad wings), and red/blue emission excess tails (red/blue tail). ML refers to the machine learning classification of the Hγ and Hδ profiles: disc (d), outflows (o) (in the form of blue-shifted absorption, broad wings, or P Cygni), and broad absorption component (ba).
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.
