Chandra X-ray spectrum of the host of T2. The upper inset shows the extraction regions used for the source (red circle) and background (with annulus). Spectra were extracted for all available observations and jointly fitted, but a single spectrum is shown for clearer inspection. Data points were fitted with an absorbed thermal component (red curve). The subtracted background is shown in blue. The ratio of the data to the model is reported in the lower inset.
