Table 3

Result of the two-tailed AD test applied to diameter dataset using the reduced MPC list.


Samples^a (binaries/non-binaries)	p-value ^b
Samples^a (binaries/non-binaries)
	μ	μ +sd	μ −sd


Full dataset (78/1011)	< 10^-7	< 10^-8	< 10^-6

According to dynamical
groups ^a:
(a) only CC (35/369)	0.005	0.0006	0.02
(b) only HC (19/274)	0.0008	0.0002	0.004
(c) only Det. and SDO (7/90)	0.06	0.02	0.18
(d) only Res. (17/251)	0.001	0.0002	0.006

Equal size ranges between
two samples (61/617)^c	0.01	0.002	0.07

Only TNOs with
D < 1142 km (75/1009)^c	< 10^-5	< 10^-6	0.0002
Only TNOs with
D > 140 km (64/615)^c	0.002	0.0002	0.014

Notes.

^(a)

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.

^(b)

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.

^(c)

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