3.4 Individual galaxy descriptions
Below, we give descriptions of each member of the UGC FR-I sample in turn. The
galaxy classifications are taken from the NASA Extragalactic Database, which lists
references in which the terms used are described. Descriptions of dust properties and
radio sources are as presented by Verdoes Kleijn et al. (1999) and Xu et al. (2000)
respectively.
NGC 193 (UGC 408) This S0 galaxy has a complex gas morphology with two
lanes apparent in the central regions (the most clearly defined lane has a width :
length = 0.18). It has a core-jet radio morphology on VLA and VLBA scales. The
STIS slits were aligned parallel to the galaxy major axis. The central kinematic and
flux properties are listed in Table 3.5; the gas does not exhibit a regular rotation
curve, though it does appear dominated by systematic rather than random motions.
The fit to the central spectrum is improved by the addition of a broad component.
Data for this galaxy are shown in Figure 3.2 (see key in Figure 3.1 for an explanation
of these plots).
