with Galactic absorption and abundance fixed to 0.3 solar; we found that a temperature of $1.18\pm 0.11$ keV provided a very good fit to the data.

For region 2 we simply fitted an [*apec*]{} model with Galactic absorption and abundance fixed to 0.3 solar to the background-subtracted data. We found a best-fitting temperature of $0.86_{-0.05}^{+0.13}$ keV.

Fitting the same [*apec*]{} model to the region at the edge of the lobes (region 3) we find a best-fitting temperature of $1.7^{+0.9}_{-0.5}$ keV. Parameters for the best-fitting models of all three regions are given in Table \[spectroanalysis\].

Radial Profiling
----------------

To characterize the extended, thermal emission around 3C452 we generated a radial profile of the X-ray emission in the 0.3 – 8.0 keV band. We binned the data adaptively to give a similar signal-to-noise ratio in each radial bin. We masked out the lobe regions to avoid any contribution from inverse-Compton emission to the radial profile, but the AGN was not masked out. We were able to do this by using two boxes to exclude the lobes as shown by the green boxes in Figure \[image\].

The particle background was modelled using the closed-filter images described in Section \[background\]. The
