================================================================================ Stellar kinematics across the Hubble sequence in the CALIFA survey: general properties and aperture corrections. (Falcon-Barroso et al. 2016) Author's address: Jesus Falcon-Barroso ================================================================================ Description: FITS tables containing the stellar kinematics of the 300 galaxies extracted from the CALIFA V1200 datacubes (v1.4) presented in Falcon-Barroso et al. (2016). The sample comprises galaxies displaying a wide range of morphologies across the Hubble sequence, from ellipticals to late-type spirals. This dataset presents homogeneously extracted stellar kinematics up to several effective radii. The paper describes the level of completeness of this subset of galaxies with respect to the full CALIFA sample, as well as the virtues and limitations of the kinematic extraction compared to other well-known integral-field surveys. In addition, it provides averaged integrated velocity dispersion radial profiles for different galaxy types, which are particularly useful to apply aperture corrections for single aperture measurements or poorly resolved stellar kinematics of high-redshift sources.
