Table 3.

Emerging architecture of the hierarchical HIP 81208 system, with the median and (16th, 84th) percentiles used for a and T.

Body	Primary	M (M_⊙)	a (au)	T (yr)
A	A	2.58 ± 0.06	–	–
B	A
C	A
Cb	C	0.0141 ± 0.0004	^(a)

Notes. Values taken from Viswanath et al. (2023) for B and C.

^(a)

We note that the distribution of the semi-major axis of Cb is not Gaussian and the peak of the distribution is at about 17 au (see text). The column “primary” indicates the parent body of each object, to which a and T also refer.
