  We have used RR Lyrae and Blue HB stars as tracers of the old Galactic halo,
in order to study the halo structure and the galactic rotation as a function of
height above the plane. Our sample includes 40 RR Lyrae and 80 BHB stars that
are about 2 to 15 kpc above the plane, in a roughly 250 sq. deg. area around
the North Galactic Pole (NGP). We use proper motions (derived from the GSC-II
database) and radial velocities to determine the rotation of the halo. From the
whole sample the motion appears to be significantly more retrograde than the
samples in the solar neighborhood, confirming Majewski (1992) results and our
own preliminary results based on 1/3 the present sample (Kinman et al. 2003;
Spagna et al. 2003). However, the better statistics has now revealed the likely
existence of two components, whose characteristics need an accurate analysis of
systematic errors on the proper motions in order to be assessed in detail.
