CHARA power-law limb-darkened diameters compared with the literature. The upper panel compares θ_PL with JMMC catalog diameters (A. Chelli et al. 2016; L. Bourgés et al. 2017), NPOI R-band diameters from E. K. Baines et al. (2025), and literature CHARA diameters (T. S. Boyajian et al. 2009; E. K. Baines et al. 2009, 2010; A. Mérand et al. 2010; P. Berio et al. 2011); the dashed line marks equality. The lower panel shows (θ_ext − θ_PL)/θ_PL in percent. The comparison is generally broadly consistent with θ_PL, with scatter dominated by source-to-source literature differences.
