Notes. N_sources represents the number of sources. The best-fit parameters for the fundamental plane correspond to the correlation coefficient of X-ray luminosity, ξ_X, the correlation coefficient of black hole mass, ξ_M, and constant offset, b (see Equation (7)). The parameter σ_R denotes the scatter of the observed L_R relative to the predicted value from the best-fit fundamental plane.
