The objective of this study is to obtain a homogeneous dataset for analyzing barium characteristics in uniform fashion. -------------------------------------------------------------------------------- Summary: The objective of this study is to obtain a homogeneous dataset for analyzing barium characteristics in uniform fashion. The analyses show that barium stars appear to have young to old disk kinematics based upon whether they are Ba weak or Ba strong. The Ba II line (4554A) is also identifiable in dwarf stars; these dwarf barium stars are small in number and weak in intensity. The analyses of the kinematics, luminosities, U,V,W velocity distributions using image-tube radial velocities and statistical parallaxes using proper motions and upsilon components show that the weak barium stars generally tend to have smaller velocity dispersion, and brighter apparent magnitudes at about same distance compared to strong Ba stars, and thus lower luminosity. The solution for the mean spectroscopic distances, the z-scale height distances and reduced proper motions also confirm the this finding.
