(1) Name of polarized source used in this paper; Source 7 (in bold) is the reference source; Source 04A and 04B are two lobes of the same radio galaxy; Source 13A and 29 (or 13B) are two lobes of the same radio galaxy.

(2) Name of associated total-intensity radio component in the Sabater et al. (2021) catalog;

(3), (4): Right ascension and declination of polarized source;

(5): Peak polarized intensity of the source in Cycle 2+Cycle 4 data;

(6): RM and RM error of polarized source in Cycle 2+Cycle 4 data;

(7): Stokes I intensity in the image of Sabater et al. (2021) at the pixel of the peak polarized intensity;

(8): Degree of polarization in Cycle 2+Cycle 4 data;

(9): Flag to indicate whether the source is listed as polarized in other catalogs. Value of 1 if the source is listed as polarized at 1.4 GHz in the DRAO ELAIS-N1 catalog (Grant et al. 2010); value of 2 if the source is listed in the NVSS RM catalog (Taylor et al. 2009); value of 3 if the source is listed as polarized at 150 MHz and 20″ resolution in the LOFAR work of Herrera Ruiz et al. (2021).

(a) Polarized source detected also in the reference epoch.

(b) Polarized source detected also in stacked Cycle 2.

(c) Polarized source detected also in stacked Cycle 4.

The bottom list (below the horizontal line) contains the polarized sources detected in the 6 to 8 σQU range.
