Summary of the main parameters of the two-infall model (2INF) adopted in this study.

	t_max,1	τ₁	τ₂	ν₁	ν₂	Σ₁	Σ₂	v_flows
	(Gyr)	(Gyr)	(Gyr)	(Gyr^–1)	(Gyr^–1)			(km s^–1)
2INF	3.25	1	1.033×R(kpc) –1.26	2	5 (4 kpc) – 0.4 (>12 kpc)	∝ e^–R/2.3	∝ e^–R/3.5	–1

Notes. All the above parameters are the same to the ones adopted in DS23. The negative sign on the radial flow speed indicates inward flows.
