33 targets with 1.4 M_⊙< stellar Mass <8 M_⊙ comparing the Q _ϕ /Fstar ratio to the system parameters of WISE 2 (W2, 4.6 μm)–WISE 4 (W4, 22 μm) color (upper right), W2–W4 color of only nonbinary systems (upper left), system age/ZAMS age (bottom left), and stellar mass (bottom right). The target shapes and colors refer to their classification (Group I-blue squares, Group II-orange circles, FS CMa-green diamonds) and the shape filling refers to the binarity (filled shapes: inner and outer binary; edge filled: outer binary; inner filled: inner binary; no filling: no binary). Outer binaries are exterior to the IWA and in the FOV as discussed in Section 3.4. Inner binaries are spectroscopic binaries from the literature. Error bars are plotted under the symbols with down pointing errors indicating the 2σ upper limit uncertainty.
