Spectra, model components, and spectral residuals for tbabs*(diskbb+nthcomp+relxillcp*nthratio). Data set 1 of Swift and NuSTAR are taken as representative. The green, red, and gray data points show the Swift, NuSTAR/FPMA, and FPMB data, respectively. The black solid line is the total model, and the orange, purple, and blue solid lines show the diskbb, nthcomp, and relxillcp*nthratio components.
