Notes. Median system properties for SL events above and below the 3σ detection threshold. Systems are classified as detectable (Yes) or undetectable (No) based on S/N > 3σ for each survey-Galactic component combination. Physical parameters include: Einstein crossing time (⟨τeff⟩ [day]), lens mass (⟨Mlens⟩ [M]]), source mass (⟨Msource⟩ [M] ), orbital period (⟨Porb⟩ [days]), total number of lensing data points (⟨ntot⟩), distance (⟨d⟩ [kpc]), and source apparent magnitude (⟨msource⟩ [mag]). Results demonstrate systematic differences in the properties of detectable versus undetectable SL systems.

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.
