Dependence between width, μ parameter and mass. One triangle represents one model. Triangles represent the model for the stellar-mass black hole accretion disks (M = 10 M_⊙), squares represent the model for the intermediate mass black hole accretion disks (M = 3 × 10⁴M_⊙) and diamonds represent the model for the supermassive black hole accretion disks (M = 3 × 10⁸M_⊙). Lines represent fits for each mass.
