Evidence of Two Kinematically Different Stellar Systems in NGC 1068
We have obtained simultaneous two-dimensional spectroscopy of the Ca II triplet lines in the central 24" x 20" of NGC 1068, using an optical fiber system. The stellar velocity field derived from these data shows a kinematic off-centering between the inner (r 3") and outer (r > 5") regions, indicative of a nonsymmetric gravitational potential. Both
