$^{\rm *}$ Fixed; $^{\rm **}$ note that this is not a statistically significant component. We use it to derive an upper limit of $L_{\rm X} \le 1.5 \times 10^{39}$ erg s-1 for the plasma component (see text for details); $^{\rm ***}$ $L_{\rm (2.0{-}10)}$ expected from LMXBs, calculated using the relation in Kim & Fabbiano (2004), taking into account the appropriate K-band luminosity and energy range.
