Top panel: the computed θ_LD for each star from the four θ_LD-photometric relationships: (K04, Kervella et al. 2004) is represented by red squares, (VB99, van Belle 1999) is represented by black circles, (Be05, Di Benedetto 2005) is represented by green diamonds, (B14, Boyajian et al. 2014) is represented by blue stars. In addition, the infrared flux method (IRFM) is also displayed as (cyan triangles). Middle panel: Δθ/θ_adopted for each star. Here Δθ_LD =θ_LD – θ_LD,adopted. The adopted θ_LD is that computed from the IRFM. Bottom panel: comparison of the T_eff for each star, computed from the θ_LD-photometric relationships, with the adopted value from the infrared flux method.
