摘要：Major and minor axis kinematics of the stellar and gaseous component of a sample of 11 Low
Surface Brightness galaxies is presented. The data, together with broad band imaging, will be
used to construct detailed mass models aimed at deriving the central density radial prole of the
dark matter component. The same data are used to study the Vcirc - sc relation for LSBs. We nd
that LSBs have a higher Vcirc at a given sc(or lower sc at a given Vcirc) when compared to HSB
and Ellipticals. This argues against the relevance of baryon collapse in the radial density prole
of the dark matter haloes of LSB galaxies.
