Velocity-dispersion (σ) maps of the 24 galaxies in our sample, seen edge on. For display purposes, we show a central area of the same 50 kpc  ×  20 kpc size for all galaxies. Horizontal dashed black lines indicate the regions where the thin disk (within the two lines) and the thick disk dominate (above and below the region between the two lines). Vertical dashed black lines enclose the central region dominated by a bar or a classical bulge. Hubble types from Table 1 are indicated on top of each panel. Pixels of 0.5 kpc  ×  0.5 kpc size, Voronoi binned to a target number of particles of 900 star particles per bin, were used to plot these maps.
