Caption: Figure 9.

The velocity and velocity dispersion measured from the emission lines as a function of pixel location along the three slit positions. We note that our spectral model required the kinematic parameters for all the detected emission lines to be the same. The highest velocity and velocity dispersion values are found at the central pixel in the vicinity of the central AGN. The velocity of the emission lines are all positive with respect to the systematic redshift of the BCG. The error bars are as in Figure 7.
