Notes. a) In the dual-blackbody fit, temperatures were kept frozen at 54 eV and 109 eV with the normalisation of the higher-temperature blackbody set to 0.13 times that of the lower-temperature blackbody, matching the XMM-Newton observation (see Section 2.3). The table lists the normalisation of the lower-temperature blackbody for this dual-blackbody scenario. b) A1 is the power-law normalisation at 1 keV.
