Maximal orbital phases a binary system can complete before a merger after reaching a GW frequency of 2435 Hz (solid lines) and 4818 Hz (dashed lines). The dashed and dotted black horizontal lines mark phases of 8π (four rotations) and 2π (one rotation), respectively, which are required to see five and three FRB subcomponents, respectively. The orbital phases were computed for binary systems with the mass of the first compact object being M₁ = 0.2 M_⊙ (blue), 1.4 M_⊙ (pink) and 100 M_⊙ (green), while the mass of the second object M₂ ranges between 0.2 and 100 M_⊙. The dot-dashed grey vertical line indicates M₂ = 1.4 M_⊙.
