Central black hole mass determination for blazars

In this paper, we used the method to determine the central black mass (M), and the boosting factor (δ), the propagation angle (Φ), and the distance along the axis to the site of the γ-ray production (d) as well for 32 γ-ray loud blazars with available variability timescales. If we take the intrinsic γ-ray luminosity to be λ times the Eddington luminosity, i.e. $L_{γ}^{in}=λ{L_{\hbox{\scriptsize Edd}}}$, then we have following results: the masses of the black hole are in the range of (0.9 ~ 101)×10⁷M_⊙(λ = 1.0) or (1.30 ~ 153)×10⁷M_⊙(λ=0.1).
