Classification of Gladman et al. (2008). CC denotes cold-classicals, HC denotes hot-classicals, Det. and SDO denote detached and scattered disc objects, Res. denotes resonant objects.


The p-value is computed using the techniques developed by Scholz & Stephens (1987). μ and μ ± sd denote p-values, calculated for the mean and mean ± standard deviation of the AD statistic, respectively.


The average number of objects. The number of objects with D > 140 and/or D < 1142 varies, depending on Monte Carlo samples.

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.
