Recent EPIC-pn spectra of SNR 1987A in the 5–8 keV range, showing the Fe K lines. The model used (red) is the sum of two components: a bremsstrahlung continuum and a Gaussian, shown by dotted lines. The bottom panels show the fit residuals. All panels have the same scale. For plotting purpose only, adjacent bins are rebinned in order to have a significant (≥ 5σ) detection in each rebinned channel. The feature seen at ~7.4 keV in the 2011 spectrum is an instrumental artefact and not an Ni K line.
