Z = redshift
V (max) = maximum of the rotation curve
Re = half light radius (effective radius)
Sigma (ap) = velocity dispersion as measured with the spectroscopic aperture
Aperture = size of the spectroscopic aperture
Sigma (Re/8) = central velocity dispersion, i.e. corrected to an effective
circular aperture of radius Re/8
(*) The velocity dispersion profile is measured.
