Table 4: Chandra ACIS-S spectral fitting results when the thermal emission model (Model 1) and the photoionized gas model (Model 2) are applied to the spectrum of the inner 10''. The last column refers to the spectrum of the extended hot gas halo instead. Fluxes are given in units of 10-13 erg cm-2 s-1, luminosities in units of 1043 erg s-1; both are corrected for absorption. * denotes a fixed parameter.
