Description:
Measurements of central velocity dispersions and heliocentric radial
velocities are presented for 94 field galaxies. Among these, 5 new
radial velocities and 80 new central velocity dispersions are
obtained. Reduction was performed independently by cross-correlation,
Fourier-quotient and Fourier-correlation-quotient methods.
