The source was selected for its large rotation measure (${\\rm RM}=345.7\\pm0.2~{\\rm rad~m^{-2}}$), substantial excess relative to the local foreground ($\\Delta {\\rm RM}\\approx171~{\\rm rad~m^{-2}}$), and strong evidence of Faraday complexity ($\\sigma_{\\rm add}/\\delta\\sigma_{\\rm add}\\approx8.6$).
