Notes. Fitting was done for spectra in the 0.2-2.5 keV range. The 3T-APEC model was used for AD Leo as it was essential. All spectra were normalised to 10 pc and binned to a minimum of ten counts per channel. N_apec is in unit of $10^{- 4} \frac{10^{- 14}}{4 π (10 p c)^{2}} {c m}^{- 5}$ $Mathematical equation: $10^{-4}\frac{{10}^{-14}}{4\pi(10 {\rm pc})^2}~ \mathrm{cm}^{-5}$$ . Luminosities are given in 10²⁷erg/s unit. A 90% chi-squared statistics error is shown.
