Fig. 12.


Top panel: velocity dispersion (green) and root mean square velocity, Vrms (red) as function of galactocentric distance to NGC 3311. Middle top panel: rotation measure V/σ. Middle bottom panel: local angular momentum parameter λ(R). Bottom panel: cumulative angular momentum parameter λ(< R) within a galactocentric distance R. In all four panels the vertical dashed line indicates the effective radius of NGC 3311. The blue, green and red curves show polynomial fits of third order to the data. Data points close to NGC 3309 and HCC 007 were excluded from the analysis.
