Notes. The tray column indicates the use of a target tray (1) or not (0). The target material listed are mixed (0), mm-sized (1), or cm-sized (2) grains. The impact outcomes are sorted as Embedding (E), Rebound (R), Rolling (Ro), or a combination of them. For rolling or rebound outcomes, the projectile coefficient of restitution (COR) is given. An estimation of the ejected mass is also listed: (0) no ejecta; (1) the ejected mass is much lower than the projectile mass; (2) the ejected mass is on the order of the projectile mass; (3) the ejected mass is much higher than the projectile mass.
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.
