Comparison between our L_⋆ estimates (see Sect. 3.1.1 and Table 2) and values reported by Ducourant et al. (2014, red symbols) and Kastner et al. (2016, black symbols), corrected for difference in distance between our adopted values and values listed in those references for individual objects. The error bars trace the individual uncertainties associated with the L_⋆ values in the compilation of Ducourant et al. (2014), and a typical uncertainty of ±0.2 dex in the other cases, for illustration purposes. The identity line is dashed in gray to guide the eye.
