Notes. The fitted model has the form tbabs × ∑ vphabs × vapec, where the interstellar absorption was fixed to 8.9 × 1019 cm-2, and the additional absorbing columns and temperatures are fixed to NH,1,2,3,4 = 0.10, 0.10, 0.71, 0. × 1022 cm-2 and kT1,2,3,4 = 0.09, 0.27, 0.56, 2.18 keV, respectively. Abundances are by number relative to hydrogen and relative to solar.
