Results of the Bayesian fitting to the observed EW_J0395 distribution.

Model	Fitting results	log 𝓛	BIC	∆ BIC

D₂	ƒ_Ca = 0.035 ± 0.007 α = −0.042 ± 0.007 a = 0.18 ± 0.03	1832	−3647	−25

Notes. The last column displays the difference in the Bayesian information criteria (BIC) between consecutive models. Negative values favor the model with lower BIC.
