Caption: Figure 3.

Left: comparison of stellar radii derived from spectroscopy+astrometry (this work) and spectroscopy alone (Johnson et al. 2017, CKS-II). The CKS-II radii are 0.7% larger on average and there is a 13.9% rms dispersion in the ratios. Right: same as left but comparing our radii to the Gaia DR2 radii. The Gaia DR2 radii are 3.0% on average and there is a 6.2% rms dispersion in the ratios.
