| Dynamics of Ringed Barred Spiral Galaxies. I. Surface Photometry and Kinematics of NGC 1433 and NGC 6300
This paper presents new near-infrared images and surface photometry andHα Fabry-Perot radial velocities for NGC 1433 and NGC 6300, twolarge and previously well-studied nearby ringed barred spiral galaxies.Stellar absorption-line radial velocities and new optical surfacephotometry are also presented for NGC 1433. The data are intended to setthe stage for dynamical modeling of the two galaxies, with the principalgoals being to derive mass distributions, bar mass-to-light ratios, barpattern speeds, and resonance locations, parameters which have beenderived for very few ringed disk galaxies. The presence of strong ringsand pseudorings in the two galaxies allows the possibility to linkspecific orbital resonances with the observed rings. The new data allowus to derive a fairly complete composite rotation curve of NGC 1433,leading us to make some interesting preliminary judgments about thestructure of the galaxy. The new data also verify the previous findingthat the radial velocity of the Seyfert nucleus in NGC 6300 differs fromthe actual systemic velocity of the galaxy by nearly 100 kms-1. We demonstrate in this paper that the offset is not anartifact of significant extinction in the inner regions of the galaxy.
| Vitesses radiales. Catalogue WEB: Wilson Evans Batten. Subtittle: Radial velocities: The Wilson-Evans-Batten catalogue.
We give a common version of the two catalogues of Mean Radial Velocitiesby Wilson (1963) and Evans (1978) to which we have added the catalogueof spectroscopic binary systems (Batten et al. 1989). For each star,when possible, we give: 1) an acronym to enter SIMBAD (Set ofIdentifications Measurements and Bibliography for Astronomical Data) ofthe CDS (Centre de Donnees Astronomiques de Strasbourg). 2) the numberHIC of the HIPPARCOS catalogue (Turon 1992). 3) the CCDM number(Catalogue des Composantes des etoiles Doubles et Multiples) byDommanget & Nys (1994). For the cluster stars, a precise study hasbeen done, on the identificator numbers. Numerous remarks point out theproblems we have had to deal with.
