1954+513(OV +591)QSO z= 1.22 V= 18.50 Notes (from the published papers): OV\,591 or QSO\,1954+513 is a 19.5 magnitude object with $z$=1.22. The 5\,GHz VLA maps from \citet{Kollgaard90} show a north-south double sided jet, with two components at 5 and 10 arcseconds north from the core, and one at 7 arcsec to the south. The early VLBI maps at 5\,GHz presented by \citet{Pearson88} show a compact structure with some extention to the North. Our map shows a jet structure extended more than 10\,mas at a P.A. of 70$^\circ$. This jet extends more than 80\,mas at 2.3\,GHz in the \citet{Fey97} images. |
