Top: NuSTAR spectra from both observations. The colors correspond to the following data sets: black: Obs I FPMA, red: Obs I FPMB, green: Obs II FPMA, and blue: Obs II FPMB. Second panel: ratio of the continuum-only model—const*tbabs*cflux*(powerlaw*fdcut)—to the data. The Fe emission line at 6.5 keV and the CRSF at ≈30 keV are clearly visible. Third Panel: ratio of the full model—const*tbabs*cflux* (powerlaw*fdcut*gabs+gauss)—fit to the data plotted with the absorption and emission line strength set to zero. The continuum is accurately fit by the power law with an exponential cutoff. Bottom panel: ratio of the full model—const*tbabs*cflux*(powerlaw*fdcut*gabs+gauss)—to the data.
