Notes. Single and double apec models were fitted to each spectrum. The absorbed and unabsorbed fluxes and unabsorbed luminosities are given in the 0.3–10 keV range. The luminosity is calculated for the assumed distance of 275 pc for SSS J122222 (Paper I) and 104 pc for GW Lib (Byckling et al. 2009). The final column gives the probability of improving the fit by including the second temperature component via the F-test.
