[107.06] A Catalog of Stellar Velocity Dispersions

Douglas B. McElroy (CSC/STScI)

A catalog of central velocity dispersion measurements is presented, current through September 1993. The catalog includes 2474 measurements of 1563 galaxies. A standard set of 86 galaxies is defined, consisting of galaxies with at least three, reliable, concordant measurements. All measurements are reduced to a normalized system using these standards. Measurements like these are useful in investigating luminosity-distance relations and ``second-parameter'' or fundamental plane problems in galactic dynamics.
