Positions and Faraday depths of all polarized sources in the catalog. The size of each symbol is proportional to the magnitude of Faraday depth (sources with |ϕ| < 5 rad m⁻² are set equal in size to 5 rad m⁻²; the largest circle is 32 rad m⁻²) while open and filled circles represent negative and positive Faraday depths respectively. The single pulsar (B1112+50) is marked with an arrow.
