(Left) Comparison of the slope of the high-energy component with the [15–50] keV luminosity, using nthcomp for observations with good low-energy coverage and a power-law for INTEGRAL-only epochs. The red line highlights the approximate luminosity threshold below which Γ stops being correlated to the luminosity of the coronal component.(Right) Hard HLD highlighting in red the observations with L_{15 − 50} below that threshold, or with a 1σ upper limit below that threshold when the BAT detection is not significant.
