a) The FGK-type Her-Lyr candidates compared with model isochrones by Yi et al. (2001), the Y² isochrones for solar mixture (Z = 0.02, Y = 0.27, OS = 0.20, l / H_p = 1.743201 [Fe / H] = 0.046320, and [α / Fe] = 0.00). M_V is displayed vs. B − V which is a well-calibrated temperature indicator for FGK-type stars. b) The M-type Her-Lyr candidates compared with isochrones by Baraffe et al. (1998), optimized for late-type stars and brown dwarfs. The V − H color index is used for the late-type stars. The photometry is taken from the Hipparcos catalog (Perryman et al. 1997), 2MASS (Cutri et al. 2003), and other catalogs if Hipparcos data were not available (Ochsenbein et al. 2000). The full list of references is given below Table 9. According to Table 11, stars denote probable Her-Lyr members, circles denote uncertain members, and squares denote non-members. In the case of stars shown without error bars, uncertainties were not given in the corresponding catalog. For conversion from apparent to absolute magnitude, we used the revised parallaxes from van Leeuwen (2007). For faint companions, we adopted the parallax of the primary.
