Notes. Column (1): central point for a given bin. Column (2): radial velocity dispersion for the sample of BHB stars in a given bin. Column (3): formal errors for the radial velocity dispersion of the sample of BHB stars. Column (4): s3 parameter for the sample of BHB stars in a given bin. Column (5): formal errors for the s3 parameter for the sample of BHB stars. Column (6): s4 parameter for the sample of BHB stars in a given bin. Column (7): formal errors for the s4 parameter for the sample of BHB stars. Column (8): number of BHB stars in a given bin.
