X-ray luminosity (L _X) as a function of peak temperature (T _p ). The upper panel shows sources where an L _X∝﹩{T}_{p}^{\alpha }﹩ relation is observed, with the best-fit α for each source shown in the legend. The bottom panel shows the source where a clear decoupling between L _X and T _p is present. The color of the markers maps the L _BB/L _X ratio between the UV/optical luminosity and the L _X following the color bar on the right side of the figure.
