Abstract:
We present results from optical spectrophotometry of 19 of the 25
lobe-dominated quasars in the 3CR complete sample. The optical spectra
were obtained with the Hale 5m telescope at Palomar Observatory,
using the blue and red CCDs of the Double Spectrograph, between 1984
and 1992. Additional data from the literature allow us to analyze
broad UV/optical emission lines in all 25 objects (100% completeness),
with a total of 191 broad-line measurements (far more than the 68
points in the preliminary results presented in the 2002 work of Hough
et al., 2002AJ....123.1258H 2002AJ....123.1258H).
