Lag – luminosity relationship based on the data of Suganuma et al. (2006) and Koshida et al. (2014). The solid line is the best-fit regression from Koshida et al. (2014). PGC 50427 (green dot) lies close to the regression line. The dashed blue line indicates the dust sublimation radius rsub expected at a given nuclear luminosity MV (from Kishimoto et al. 2007).
