Results of the apec+pl fit to the spectrum of Wd 1. Upper panel: Black data points are the source spectrum, gray data points are the background as measured in the background region. Both are binned to a minimum significance of 5σ. The overall model is given in black, while the apec component is red and dashed, the powerlaw component is light blue and dashed-dotted, and the GX 340+0 halo component is dark blue and dotted. Lower panel: Normalized residuals of the source spectrum (black) and of the background spectrum (gray).
