Spectral analysis results with the contour-binning method, using the TBABS × NEI model for the source emission, in Galactic co-ordinates. In (a) we show the reduced χ² for the fit, in (b) the plasma temperature, kT, in keV, in (c) the ionisation timescale, τ in cm⁻³ s, and in (d) the normalisation of the plasma component, normalised to the respective area of the bins for comparability, in cm⁻⁵ arcmin⁻². The approximate outline of the Antlia SNR is indicated by a yellow region.
