High-resolution (2″) fractional polarization maps at VLA L-, S-, and C-bands. The relic is polarized at all of the observed frequencies, reaching values up to 50% in some regions. The northern part of the relic strongly depolarizes at 1.5 GHz. Contour levels are drawn at and come from the S-band Stokes I image. These maps are corrected for the Rician bias. The beam sizes are indicated in the bottom left corner of the each image. The image properties are given in Table 1, IM1, IM5, and IM9.
