Distribution of BH masses inferred with the luminosities obtained from the m_F444W magnitude, compared to our reference model α = 1 and β = 0.6 (filled red histogram). The top panel assumes an Eddington fraction ϵ_Edd = 10⁻³. The bottom panel assumes ϵ_Edd = 10⁻⁴. The colored lines show the mass distributions for the standard BC (BC = 8.0, green), the minimum (BC = 3.1, blue), and the maximum (BC = 21.0, orange).
