VizieR Online Data Catalog: Peculiar velocities in 6dFGS (Springob+, 2014)
Abstract
The details of the sample selection and data reduction are presented in Magoulas et al. (2012MNRAS.427..245M) and Campbell et al. (2014MNRAS.443.1231C, Cat. J/MNRAS/443/1231). In brief, the 6dFGSv includes all 6dFGS early-type galaxies with spectral signal-to-noise ratios greater than 5, heliocentric redshift zhelio<0.055, velocity dispersion greater than 112km/s, and J-band total magnitude brighter than mJ=13.65. The galaxies were identified as 'early-type' by matching the observed spectrum, via cross-correlation, to template galaxy spectra. They include both ellipticals and spiral bulges (in cases where the bulge fills the 6dF fibre). Each galaxy image was subsequently examined by eye, and galaxies were removed from the sample in cases where the morphology was peculiar, the galaxy had an obvious dust lane, or the fibre aperture was contaminated by the galaxy's disc (if present), or by a star or another galaxy.
