Same analysis as in Fig. 22, but for HD 156292. Final model (red) with Ṁ = 1.5 × 10⁻⁹M_⊙ yr⁻¹ and log (L_⋆ ∕ L_⊙) = 5.12. Top panel: models with the limits on Ṁ (7.5 × 10⁻¹⁰M_⊙ yr⁻¹ in green and 5.5 × 10⁻⁹M_⊙ yr⁻¹ in blue): fixed log (L_⋆ ∕ L_⊙) = 5.12. Bottom panel: models with the limits on log (L_⋆ ∕ L_⊙) (4.92 in green and 5.32 in blue): fixed Ṁ = 1.5 × 10⁻⁹M_⊙ yr⁻¹. We note that the error bars of log (L_⋆ ∕ L_⊙) do not produce any significant changes on the UV diagnostics for Ṁ.
