Temperature asymmetry towards (first panel) the M 104 galaxy in μK (with the standard errors) of the Variant 1 (A2A3–A1A4), in the four considered Planck bands (see text for details) within four radial distances of 0.2° (R0.2), 0.4° (R0.4), 0.6° (R0.6), and 1° (R1.0); and (second panel) the same for the 360 control fields with the same geometry equally spaced at one degree distance from each other in Galactic longitude and at the same latitude as M 104.
