The 1.4-GHz image of J0813+3508 from the VLA FIRST survey (White et al. 1997). The peak brightness is 22.5 mJy/beam, the lowest contour levels are drawn at  ± 0.25 mJy/beam, the positive contour levels increase by a factor of 2. The circular Gaussian restoring beam size is  (FWHM), as indicated in the lower-left corner. The northwestern radio companion (top right) is catalogued as another source in FIRST,  away from the quasar (in the centre).
