Table 3

Prior ranges of the Sérsic parameters for the lens galaxy light.

Component	Parameter	Description	Prior	Prior range/value
	x_S["]	x-centroid	Gaussian, Flat prior in SSB reconstruction	Centered on starting value, Gaussian
				σ= 0.3
	y_S["]	y-centroid	Gaussian, Flat prior in SSB reconstruc-	Centered on starting value, Gaussian
			tion	σ= 0.3
	q_S	Axis ratio	Flat	Single-band: [0.3,1], multi-band: [0.1,1]
Sérsic	ϕ_s [°]	Position angle	Flat	[0, 360]
	A_S	Amplitude	Flat	[0.01, 10]
	r_eff ["]	Effective radius	Flat	[0.01, 10]
	n_S	Sérsic index	Flat	Single-band: [0.5, 6], multi-band: [0.4,9]

Notes. The Sérsic parameters are varied during lens light modeling and the modeling of the arc light with SSB reconstruction. The position angle is measured counterclockwise from the positive x-axis (east of north).
