Caption: Figure 6.
4.5–78.4 keV NuSTAR FPMA (black) and NuSTAR FPMB (red) spectra and the 0.7–10 keV Swift (blue) spectrum of 4U 1728-34, fit with the reflionx relativistically blurred reflection model where the column density is fixed to 2.9 × 1022 cm−2 (model 2). (a) Residuals of the reflection model. (b) ﹩\nu {F}_{\nu }﹩ plot with individual model components: blackbody (dashed and dotted), cutoff power law (dashed), and reflionx (dotted).
