Notes.

^(a)

Both components in YY Gem A/B, AT Mic A/B, and BL/UV Cet are expected to have the same spectral type.

^(b)

Distances derived by HIPPARCOS and Gaia.

^(c)

The EUV and X-ray values give luminosities in the 10–36 nm and 0.517–12.4 nm (2.4–0.1 keV) range. Ly-α luminosities in parentheses are estimated using Eq. (23) and measured values were reported by Wood et al. (2014) for π¹ UMa, Linsky et al. (2014) for YZ CMi, and Wood et al. (2005) for the rest.

^(d)

The radius of GJ 117 is estimated from the stellar models of Spada et al. (2013) assuming the mass and age (150 Myr) given by Vigan et al. (2017).
