Model SEDs (color lines) compared to the observed ones (black). The IUE/SWP+LWP and photometric data are listed in Table 1. Flux unit is in erg cm⁻² s⁻¹ Å ⁻¹ and wavelength is in Å. Model SEDs in solid lines are computed with distances from Gaia DR2: 1 ∕ (π + σ_π) (green), 1 ∕ π (red), 1 ∕ (π − σ_π) (blue). Model SEDs taking into account Hipparcos distances are shown in dotted lines (HD 116852). For the stars listed in Table 4, we show two set of models with different values of E(B − V) and R_V from our assumption and from Wegner (2003). For HD 36861, there are shown four sets of models with different extinction parameters, including one with E(B − V) and R_V from Wegner (2003). For HD 218195, we compare two sets of models with different values of E(B − V). For HD 116852 and HD 218195, SED models considering the distances of 4.8 and 2.5 kpc are shown in red dashed line.
