   FIG. 11. 3C 293. The two faint components have much steeper spectra than the
 main bright component. The distribution of faint sources in the field of this
 source is most unusual. The objects marked are (a) galaxy, 14.3 mag, redshift
 0.0452 (W2) (27), (b) faint 19.5 mag red galaxy, (c) neutral colour object,
 close to print limit on both red and blue prints.
