Abstract (from CDS):

We present the results of the analysis of a set of medium-resolution spectra, obtained by the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope, of the emission-line gas present in the nuclei of a complete sample of 21 nearby, early-type galaxies with radio jets (the UGC FR-I Sample). For each galaxy nucleus we present spectroscopic data in the region of Hα and the derived kinematics.

We find that in 67% of the nuclei the gas appears to be rotating and, with one exception, the cases where rotation is not seen are either face-on or have complex central morphologies. We find that in 62% of the nuclei the fit to the central spectrum is improved by the inclusion of a broad component. The broad components have a mean velocity dispersion of 1349±345 km/s and are redshifted from the narrow line components (assuming an origin in Hα) by 486±443 km/s.
