NED object is PKS 2006-56; Reference is 1982MNRAS.198..259G

   Figure 1. Contour map of the central region of 2006-56 at 1415 MHz. Galaxies
 a,b,c (i, ii, iii) (notation of Schilizzi & McAdam 1975) are shown where the
 point source 2007-566 has been subtracted is indicated by (*). The crosses (x)
 indicate the positions of other galaxies in the cluster {cf.Plate 2). The
 contours are -9 (dashed), 9, 18, 27, 36, 45 mJy per beam where 9mJy per beam
 corresponds to 2.4 K beam brightness. The size of the synthesized beam is
 indicated.
