Fig. 4.
XMM-Newton and NuSTAR spectrum of IRAS 23226-3843. The data are corrected for the effective area of the instruments (using the “setplot area” command in XSPEC) but are not unfolded. Solid lines show the best-fit model, and shaded regions show the background spectra. The lower panel shows the residuals to the best-fit model. For clarity, we show only the EPIC-pn and NuSTAR data. The two NuSTAR FPM spectra are grouped for clarity in the figure, but fitted separately.
