   Figure 1. (e) Hybrid maps of nine sources. Ten logarithmically spaced
 contours are plotted, ranging from the peak brightness, P, to the lowest
 brightness L at which most of the features on the map are believed to be real.
 The contour interval K is defined by K = (P/L)**(0.1), and the levels plotted
 are K**(n)L for n = 0, 1, 2, ... 9. Each map is labelled with values for P (in
 units of mly per beam area) and L (as a percentage of P). The angular scale is
 indicated along the sides and the circular Gaussian restoring beam, FWHM = 0.9
 arcsec, is shown in the bottom left-hand corner of each map.
