Three representative spectra of NGC 7679 with the best-fit modeling for the LHS (ID = 40631001, left) using the BeppoSAX data, HIMS (ID = 66019000, center) from ASCA and for the IS (ID = 00088108002, right) from Swift in units of E * F(E) using the tbabs*(bmc+gauss) model, respectively. The data are denoted by crosses, while the spectral model is shown by a red histograms for each state. o model the line component, we used Fe XXV/Fe XXVI K_α (pink) lines with energies of 6.7/6.9 keV. Bottom: Δχ vs photon energy in keV.
