Comparison of the stellar velocity dispersion maps and radial profiles from the CALIFA and DiskMass surveys. Each row shows (from left to right): a color-composite SDSS image of the galaxy, the DiskMass velocity dispersion map (see Sect. 5 for details), the CALIFA velocity dispersion map, and the radial velocity dispersion profile (extracted in circular annuli). DiskMass measurements are in gray while the CALIFA measurements are in color following the same color scheme of the maps (also indicated with the colorbar below). Empty (i.e., white) regions within some of the CALIFA maps are areas masked during our kinematic extraction. All velocity dispersion measurements are expressed in km s^-1.
