Notes. Column 1: source name used in the present paper; Col. 2: source name used in the Stokes I map, taken from Sabater et al. (2021); Cols. 3 and 4: right ascension and declination (J2000) of the polarized source, in degrees; Cols. 5 and 6: peak polarized intensity of the source, in mJy beam−1, in the reference epoch and the stacked data, respectively; Cols. 7 and 8: S/N of the source in the reference epoch and the stacked data, respectively; Cols. 9 and 10: Faraday RM of the source and its error, in rad m−2, in the reference epoch and the stacked data, respectively (RM synthesis parameters described in Sect. 2.3); Col. 11: peak intensity of the source on the Stokes I map, taken from Sabater et al. (2021) (6′′ angular resolution), in mJy beam−1; Cols. 12 and 13: fractional polarization of the source, calculated using both the polarization and the Stokes I maps at 20′′ angular resolution, on the reference epoch and the stacked data, respectively. (*) The RM of source 06 had to be calculated separately since the peak of the Faraday spectrum is located very close to the limit of the instrumental polarization range.
