                         tracer of the AGN ionizing continuum, a novel BH-mass scaling 
                         relation of the form log(M-BH) = (6.40 +/- 0.17) - (1.99 +/- 0.37) 
                         x log ([Si VI]/Br gamma(broad)), dispersion 0.47 dex, over the BH 
                         mass interval, 10(6)-10(8) M-circle dot is found. Following on the 
                         geometrically thin accretion disc approximation and after 
                         surveying a basic parameter space for coronal lines production, we 
                         believe one of main drivers of the relation is the effective 
                         temperature of the disc, which is effectively sampled by the [Si 
                         VI] 1.963 mu m coronal line for the range of BH masses considered. 
                         By means of CLOUDY photoionization models, the observed 
                         anticorrelation appears to be formally in line with the thin disc 
                         prediction T-di(sc) proportional to M-BH(-1/4).",
