   Figure 2. A contour map of the Einstein HRI image of NGC 4649 after
 smoothing with an 8 arcsec 2-D Gaussian function. The lowest contour level
 represents a surface brightness of 1.0 x 10**(-6) cts**(-1) arcsec**(-2) which
 is 3{sigma} above background and 8 per cent of the peak surface brightness.
 All other levels increment by 10 per cent of the peak value.
