The objects from which the structure and the kinematical properties of the nuclear region and the halo can be derived are in general those classified as population II objects: the RR Lyrae variables, population II Cepheids, RV Tauri variables, long-period variables with periods near 200 days, novae, planetary nebulae, bright red giants as found in globular clusters, and the blue stars found near the galactic poles which are probably similar to those found in globular clusters.
