Comparison of the slopes (top) and intercepts (bottom) of the log L_acc − log L_lines empirical relations derived in this work with those from Alcalá et al. (2017). The colorbar indicates the corresponding wavelength of each accretion tracer, ranging from UVB (blue) to NIR (yellow). Dark and light gray regions represent agreement within 1σ and 2σ, respectively. Accretion tracers not in agreement within 1σ (2σ) within the error are plotted as squares (triangles).
