Electrographic UBV Photometry of the Jet in 3C 273
Abstract
Magnitudes in the UBV system have been determined for the jet in 3C 273 by means of the electronic camera. The precision of the magnitudes is limited by the determination of that portion of the background light contributed by scattering and diffraction from the QSO. Key words: electrographic photometry - quasi-stellar object
