Scientific paper

We discuss the dependence of the velocity dispersion measurements on different stellar libraries used as stellar templates. Apart from the well known blue part of the spectrum, we have also tested the red spectrum around the Ca+Fe feature at 6500 Å, following the prescription of Ho et al. (2009). We have measured the velocity dispersions of a sample of nearby galaxies of various Hubble types taken from the Sloan Digital Sky Survey (SDSS) and we discuss the obtained results.
