XMM-Newton EPIC-pn spectrum of MCSNR J0512−6707 from Obs. ID 0741800201, shown alone for clarity. In each panel the best-fit model is given by the solid black line, the purple dash-dot lines mark the AXB components, the blue dash-dot-dot-dot line shows the combined contributions of the QPB, residual SPs, instrumental fluorescence lines, and electronic noise. Left: best-fit vapec model shown by the dashed red line. Right: best-fit vapec+powerlaw model shown by the dashed red line and dashed green line, respectively. The model fit parameters are given in Table 1. Note that the instrumental fluorescence line normalisations are free in each fit and adjust themselves according to the residuals at their respective energies.
