Results of the fitting procedure. Left: transition radius r_J (from r_isco to 300) between the JED and the SAD. Right: mass accretion rate ṁ_in. Each side is divided vertically between the four outbursts and horizontally between the rising and decaying phase of each outburst. The green solid line represent the results from M19 and M20, and the green region indicates where the minimization function varies by less than 10% with respect to its minimum. The blue dashed line shows the results of the fitting procedure and the black vertical bar the associated 90% confidence range. The decaying phase of outburst 4 is the subject of Appendix B.
