Table 2

Range and sampling method of the stellar labels of Kurucz ATLAS12 models, calculated for the HOTPAYNE spectral modeling (see Sect. 4).

Labels	Range	Sampling
Teff	[7500, 60 000] (K)	MIST
log g	[0, 5]	MIST
[Fe/H]	[−3,0.5]	MIST
v_mic	[0, 15] (kms⁻¹)	Random
vsini	[0, 500] (kms⁻¹)	Random
N_He/N_total	[0, 0.25]	Random
[C/Fe]	[−2,3]	Random
[N/Fe]	[−2,3]	Random
[O/Fe]	[−2,3]	Random
[Si/Fe]	[−1,2]	Random
[S/Fe]	[−1,2]	Random

Notes. The MIST sampling method means we draw from the MIST grid uniformly with equivalent evolutionary phases.
