Deconvolved flux spectra fitted with different models and corresponding residuals. Left panel: model composed of diskbb (dash-dotted line) and thcomp*bbodyrad (dashed line), with residuals showing the presence of reflection features. For the sake of clarity, only NICER and NuSTAR data are shown. Right panel: model including relxillns (dotted line). The data from NuSTAR/FPMA and FPMB were combined (with setplot group in XSPEC) for plotting purposes only.
