Slope of the single and segmented power-law fits to the log L_* − log L_acc (top panel) and log M_∗ − log Ṁ_acc (bottom panel) relationships for the four regions studied in this work. The slopes of the single power-law fits are shown with circles, of the faint and low-mass samples with squares and the bright and high-mass samples with stars. A small offset in age in the slopes of each region was performed for visualization purposes. The symbols follow the same color-coding as in Fig. 5.
