Notes. N denotes the number of objects in the model in each magnitude bin (not to be confused with NG which denotes the number of simulated objects in magnitude bin G); wG denotes the relative, normalised weight of each bin, such that 
; P∗ ,min and P∗ ∗ ,min denote the minimum-required detection probabilities for single and double stars, respectively (Eq. (16)). The square root indicates that P refers to either the high- or the low-frequency detection probability; the final detection probability is the logical AND (i.e., the product) of these probabilities.
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.
