NED object is 3C 319; Reference is 1983MNRAS.203..147M

   Figure 4. The distribution of {alpha}(5.0, 2.7) for 3C 319. Values are given
 where I_5.O_ > 20 mJy, and they are plotted on a grid of 9 X 10 arcsec**(2).
 They are superposed on the 2.7-GHz map of I-Q, which has contour intervals ot
 3 mJy up to 30 mJy (with the zero level omitted), and 30 mJy thereafter.
