Panel a: above a critical value of the product of the X-ray attenuation coefficient, a, times the ejection/accretion ratio, f (Eq. (10b)), solutions for the inner disk accretion rate multifurcate. Panel b: domains of solutions to Eqs. (10a) and (10b) in $a\dot{f}$ vs. the maximum PE rate. Contours are the ratio of the maximum to minimum values of ${\dot{M}}_{\text{acc}}$ expressed in dex. The dotted line is the parameter range for the case shown in the top panel.
