Various spectral model fits to the spectra of 4XMM J174917.7–283329. The black, red, and green represent the spectra from the EPIC-PN, MOS1, and MOS2 detectors, respectively. Panel A represents the best-fit spectral model overlaid on the data points. The lower panels indicate the ratio plot obtained from the fitting of various models. The model components are tbabs (the Galactic absorption), tbpcf (the absorption from a medium partially covering the X-ray source), po (the power-law continuum), apec (emission from collisionally ionized diffuse gas), mcvspec (the continuum emission from the WD accretion column), g1 (the Gaussian line at 6.4 keV), and g2 (the Gaussian line at 6.7 keV).
