Figure 1. Brightness distributions of 15 nearby radio galaxies at 2.7GHz.
For each source, details of the map are given. Maps at 2.7 GHz are from the
5-km telescope and are of I - Q. The zero contour level is suppressed on the
maps and negative contours are dashed. Unless otherwise noted, the contour
interval is 3 mJy per beam area for 5-km maps. Details are given of any
unusual map processing. A cross marks the position of the associated galaxy's
nucleus, as given by Dressel & Condon (1976). The formal accuracy of these
positions is +/- 4 arcsec. Map coordinates are for epoch 1950.0. The L-shape
in the map corner gives the FWHM of the beam in right ascension and
declination. The FWHM in right ascension of the beam is 3.6 arcsec at 2.7 GHz
at full resolution, and is larger in declination by a factor cosec {delta}.
NGC 4839. The contour interval is 2 mJy per beam area. The associated object
is a very elliptical cD galaxy (Oemler 1976).
