  A procedure is described of construction of velocity fields and velocity
dispersion of the stellar component in the central regions of galaxies on the
basis of data obtained with the integral field spectrograph MPFS.
Cross-correlation and Fourier quotients techniques adapted for 2D spectra
reduction are used. A detailed discussion is given of the problems of providing
for the instrumental profile in measuring the velocity dispersion. Using the
existing version of the spectrograph, one can measure radial velocities and the
dispersion of velocities to an accuracy of 5-10 km/s and 10-15 km/s,
respectively. As an example the double-barred galaxy NGC2950 is considered.
