Blackbody luminosity versus temperature measured from the red envelope in LRDs (circles) and the local analog “The Egg” (star). The dashed and dotted lines show the predicted blackbody luminosity and temperature from the outflow model at different black hole masses (M = 10⁵, 10⁶, and 10⁷ M_⊙) and accretion rates (﹩\dot{m}=1500﹩, 3000, and 5000).
