The optical spectra of this source presented by Richstone et al. (1980) and
Osmer et al. (1994) show several strong broad emission lines. This source is
also part of the FIRST survey (Becker et al. 2001) and the SDSS (Schneider et
al. 2003). The source remains unresolved in the radio on the scales imaged (Fig.
7d). Similarly, the VLA B configuration map from the FIRST survey at 20 cm shows
only an unresolved core.
