Fig. 1
Energy-coded three-colour image of the XMM-Newton field of view around HD 45314. The left and right panels correspond to the observations of April 2012 and March 2016, respectively. HD 45314, the object in the centre of each panel, appears bluer and brighter in the April 2012 observation. For each epoch, the data from the three EPIC instruments were combined and exposure corrected. Red, green, and blue colours correspond to photon energies in the ranges [0.5, 1.0], [1.0, 2.0], and [2.0, 8.0] keV, respectively.
