Rest-frame Fe K band spectrum of IRAS F00183–7111. Data obtained from XMM-Newton EPIC cameras, Chandra ACIS-S, Suzaku XIS, were combined. The data are in flux density in units of 10^-14 erg s^-1 cm^-2 keV^-1. The Fe line feature peaks at 6.7 keV and has a moderate width of σ ~ 0.15 keV. For reference, the blueshifted absorption model for the NuSTAR spectrum discussed in Sect. 3.2.3 (IABS2 in Table 2), supplemented by a Gaussian line for the Fe K feature, is overplotted by the histogram in grey. The continuum level is corrected for the flux difference (see Sect. 3.2.2). The blueshifted Fe xxv absorption line at 8 keV predicted by the absorption model seems to be matched by the data.
