Upper graph: dependence between period and width of flares for a stellar-mass black hole (M = 10 M_⊙). The graph was prepared for a range of μ ∈ [ 0.44:0.8 ]. Middle graph: dependence between period and width of flares for an intermediate-mass black hole (M = 3 × 10⁴M_⊙). The graph was prepared for a range of μ ∈ [ 0.44:0.8 ]. Lower graph: dependence between period and width of flares for a supermassive black hole (M = 10⁸M_⊙). The graph was prepared for a range of μ ∈ [ 0.44:0.56 ]. The colored lines represent isolines for different μ.
