Notes. The fluxes and luminosities were derived from the best-fit models of fitting spectra in 0.2-2.0 keV for M stars and 0.35-2.0 keV for FGK stars. For the 0.1-2.4 keV band, corresponding to the ROSAT band, the values were obtained by extrapolating these best-fit models. Fluxes are presented as if one average source were located at 10 pc. The uncertainties here are the conservative union of the 90% χ2 statistical confidence intervals and the systematic offset between the AC and AR stacking methods.
