Planck fields toward Cen A galaxy in which our analysis is performed are shown. The radius of the outer circle is of 5° about the NGC 5128 center (with Galactic coordinates l = 309.52°, b = 19.42°). The northern field (with 10792 pixels), corresponding to the GLN radio lobe, has Galactic coordinates 308.65° ≤ l ≤ 311.03 and 19.64° ≤ b ≤ 23.92°, while those of the southern field (which has 11011 pixels), corresponding to the GLS, are 307.98° ≤ l ≤ 310.64 and 15.58° ≤ b ≤ 19.14°.
