Polarization information of the sources at C and X bands. For each plot, first upper panel: the total intensity S expressed in [mJy] (the black line simply connects the points), second panel: the polarized flux density S_pol expressed in [mJy], the Stokes parameters Q (magenta dots) and U (green dots) expressed in [mJy] (the black, the magenta, and the green lines simply connect the points); the third middle panel reports the fractional polarization; the last bottom panel shows the polarization angle χ expressed in [deg]. All this information is represented in the λ² domain. Thevertical dashed lines indicate the C to X band range.
