Extracted surface brightness profile for MACS0025. In the upper panel, the solid line shows the best-fit model to the overall surface brightness. The background level is denoted by the horizontal, dashed line while the dotted curve indicates the underlying, background-subtracted model. The lower panel indicates the difference between data and model relative to the error at each radius. For both panels, the radius, R_maj, corresponds to the radial distance along the semi-major axis of the assumed elliptical distribution. The model is discussed in the text.
