Spectroscopic observations of radio sources.
Abstract
Results are presented for spectroscopic observations of 34 extragalactic radio sources over the spectral range from 3200 to 5700 A mostly with a reciprocal dispersion of 240 A/mm. The data include finding-chart or identification references, wavelengths of observed lines, qualitative descriptions of each line by strength and width, suggested line identifications, corresponding individual redshifts, and mean redshifts. Twenty-four of the sources are listed as QSOs, two as galaxies, and eight as objects with continuous or inconclusive spectra. It is noted that one of the QSOs has the spectrum of a Seyfert galaxy, one QSO has an exceedingly rich absorption-line spectrum from 3200 to 4800 A, two QSOs are of indeterminate redshift, and two objects with continuous spectra are BL Lac objects.
