On the Use of UBV Data for Kinematically Selected Samples to Determine the Dependence of Kinematics on Abundance Norris, John E. ; Ryan, Sean G. Abstract An analysis of errors that may affect the Sandage and Fouts (SF, 1987) analysis of UBV data for a kinematically selected sample of stars was carried out. In particular, the effect of propagation of errors associated with such factors as observational parameters, abundance calibration, distance determination, the neglect of reddening, and the assumption that only dwarfs are included on the SF analysis was evaluated. It is demonstrated that the large abundance errors in the Sandage and Fouts analysis of the UBV data of their sample, together with their coarse abundance binning of the data, preclude the possibility of their testing for a decoupling of the halo from the disk.
