Notes. Column (1): inner point for a given bin (in kpc). Column (2): outer point for a given bin (in kpc). Column (3): systemic velocity of the stars in a given bin (in kms-1). Column (4): error for the systemic velocity of the stars in a given bin (in kms-1). Column (5): rotation amplitude of the stars in a given bin (in kms-1). Column (6): error for the rotation amplitude of the stars in a given bin (in kms-1). Column (7): f′ fraction (see text for details). Column (8): number of BHB stars in a given bin.
