Parameters, priors, and prior ranges.

Parameter	Component	Prior type	Prior range
Age [Gyr]	SSP	uniform	[0,15]
Z/Z_⊙	SSP	uniform	[0.01, 3]
τ [Gyr]	general	uniform	[0,0.8]
log(M_★/M_⊙)	general	uniform	[6, 15]
σ_★ [km/s]	general	𝒢(val, err)	[0, 400]
A_V [mag]	dust	uniform	[0, 4]
n	noise	uniform	[1, 10]
C_i i = 0
i = 1, 2		calibration	𝒢(1,0.1)
𝒢(0,0.1)	$[0.75, 1.25]$
$[- 0.25, 0.25]$

Notes. The 𝒢(x, y) stands for a Gaussian prior centred on x with dispersion y. In the case of σ_★, val and err refer to each galaxy’s velocity dispersion and associated error, measured as described in Sect. 2.
