SMBH mass and bolometric luminosity of J0647_1045 in comparison with measurements for other LRDs from the literature (Harikane et al. 2023; Kocevski et al. 2023; Kokorev et al. 2023; Larson et al. 2023; Furtak et al. 2024; Greene et al. 2024; Maiolino et al. 2023; Matthee et al. 2024). The symbols are as indicated in the legend, and the colour-scale represents redshift. The filled magenta star shows SMBH mass and L_bol estimates for our source, derived from a broad Hα line using a dust correction of A_V = 5.61 ± 0.04, corresponding to the AGN extinction from our model. The empty magenta star shows these properties corrected by A_V = 0.9 ± 0.4, which corresponds to Balmer attenuation. The empty black star shows measurements for our source with no dust correction applied.
