Fitting results with the reflection model BBODY+DISKBB+RELXILLLP for the XMM-Newton/RXTE observations of 4U 1636–53. The fitted spectra and the individual model components (main panel), and the residuals in terms of sigmas (subpanel) for the six observations are shown. The components BBODY, DISKBB, RELXILLLP, and the sum of all these model components are plotted with a cyan dash-dotted line, black dotted line, blue dashed line, and purple line, respectively.
