2D surface brightness fit. Left: LCDCS 0504 image in the [0.5–7.0 keV] band with point sources and artifacts (CCD gap) masked out. Middle: best-fit β-model (see text for details) shown with the same color coding as the original image. Right: residuals, data minus best-fit model. No apparent structure is seen in the residual image.
