Instability map in the hot disc case for μ₃₃ = 15. Left: outburst amplitude defined as A = Ṁ_max/Ṁ_tr; here, Ṁ_c = 2.8 × 10¹⁸ g s⁻¹. Right: logarithm of the recurrence time measured in days. Regions labelled ‘RI’ and ‘RII’ correspond to the magnetic gating instability with the same label as in DS10. The white (left panel) and black (right panel) dots indicate the position of the light curve shown in Fig. 8
