Scientific paper

We will present an investigation of the systemic radial velocity distribution of cataclysmic variable stars (CVs). We have critically mined the astrophysical literature published until 2007 September, resulting in a dataset of 308 systemic radial velocities found using emission and/or absorption lines. From these data, we find the solar motion and velocity ellipsoid parameters for three groups: (1) all CVs, (2) nonmagnetic CVs (dwarf novae and UX UMa novalike variables), and (3) 66 magnetic CVs (AM Her/Polar stars and DQ Her/Intermediate Polar stars). We find the kinematics of CVs to be consistent with a moderately old disk population.
