Comparison of the spectral shapes of the 8.5 keV Gaussian (red dotted line) and a black body with kT = 2.7 keV (blue dotted line). The total flux is the same for both components. When added to the cutoff power-law continuum (black solid line) the Gaussian is much more prominent (red dashed line) than the black body (blue dashed line). We note that the spectra are shown as radiated power (νF_ν) over the energy E = hν.
