Table 3.

Best-fitting parameters of the distance distributions for the initial (first row) and survived (second row) samples of clumps.

Config.	Face-on	Edge-on	Spherical
p(R ; θ)	p_exp(R ; R_e)	p_exp(R ; R_e)	p_Sersic(R ; R_e, n)
θ	R_e/kpc	R_e/kpc	R_e/kpc, n

Initial	$2 . 52_{- 0.5}^{+ 0.68}$ $2.52^{+0.68}_{-0.5}$	$4 . 06_{- 1.02}^{+ 1.55}$ $4.06^{+1.55}_{-1.02}$	$2 . 41_{- 0.75}^{+ 0.69}, 0 . 70_{- 0.11}^{+ 0.25}$ $2.41^{+0.69}_{-0.75},0.70^{+0.25}_{-0.11}$
Survived	$3 . 30_{- 0.21}^{+ 0.23}$ $3.30^{+0.23}_{-0.21}$	$3 . 92_{- 0.21}^{+ 0.22}$ $3.92^{+0.22}_{-0.21}$	$2 . 13_{- 0.16}^{+ 0.12}, 0 . 59_{- 0.02}^{+ 0.04}$ $2.13^{+0.12}_{-0.16},0.59^{+0.04}_{-0.02}$

Notes. As described in Sect. 2.4, the distance distribution is modelled as an exponential function for the face-on and edge-on disc cases, and as a de-projected Sérsic profile for the spherical case. Uncertainties are given at 1σ.
