Notes. The fitted model has the form wabs ∗ phabs ∗ (apec + apec), with the first absorption fixed to 1.14 × 1022 cm-2, the temperatures fixed at 0.22 and 1.19 keV, and the ratio of normalization factors norm1/norm2 fixed at 14.93 for the Swift, Suzaku, and ROSAT data. Error bars and energy bands are the same as in Table 2.
