VizieR Online Data Catalog: Gas dynamics in tidal dwarf galaxies (Lelli+, 2015)

HI datacubes in FITS format for 3 interacting and post-interacting systems that contain tidal dwarf galaxies. The channel maps are in equatorial coordinates and in units of Jy/beam. The spatial and velocity resolutions of the datacubes are listed in Table 6 of Lelli+2015. The observations and data reduction of NGC 7252 are described in the paper. The cube of NGC 4694 was derived by Duc et al. (2007A&A...475..187D) using C-array VLA data from the VIVA survey (Chung et al., 2009AJ....138.1741C). The cube of NGC 5291 was derived by Bournaud et al. 2007, Science, 316, 1166 using multi-array VLA observations. This cube was "cleaned" following the same procedures as the THINGS survey (Walter et al., 2008AJ....136.2563W, Cat. J/AJ/136/2563), which provide a rescaled cube with correct flux densities and a non-rescaled cube with uniform noise structure (useful for visualization purposes and kinematic studies). We provide the flux-rescaled cube only.
