Ages and bolometric luminosities of our benchmark targets (Table 2), color-coded by spectral types. We use open circles to mark the benchmarks excluded from the evolution model analysis, including binaries and several objects whose ages and/or Lbol fall outside the convex hull of the evolution models (see Section 3). The Sonora Diamondback hybrid-grav evolution models (black lines) with [M/H] = 0 dex are overlaid.
