Comparison of unfolded pn spectra obtained during the three XMM-Newton observations. All spectra were fitted using a black-body model. The spectra were rebinned for display purposes. The observations were obtained during quiescence in 2007 (black crosses and dotted line; ObsID 0505280101), ∼90 days after the end of the 2015 outburst (blue up-pointing triangles and dashed line; ObsID 0790189391), and ∼140 days after the end of the 2017 outburst (red squares and solid line; ObsID 0804940201).
