A 0.2–10 keV XMM-Newton MOS1 X-ray image containing the two X-ray sources of interest: the compact source 3XMM J204920.4+290107 that we identify as a Seyfert galaxy, 2MASS J20492048+2901070, and the extended source 3XMM J204914.4+290324 corresponding to the cluster whose dominant galaxy is 2MASX J20491447+2903237. The source spectral extraction regions are indicated by the circles.
