Radial profile around PSZ2G259.98-63.43 for the three SPT channels (95-150-220, upper panels) and four Planck channels (100-143-217-353, lower panels). The black dots represent the radial average on the SZ maps, the red line is the best fit of the cluster profile, and the blue line is the radial mean of the total background signal. For Planck data, we also show the individual components of the background model: the dotted cyan line is the CMB, the dashed red line is the GTD, and the dash-dotted orange line is the cluster dust component.
