Notes. The first three rows correspond to the combination of turnoff and RGB populations which should be dominated by bulge populations (Kuijken & Rich 2002) and according to the cuts in Fig. 12. Last 6 rows are the parameters for the velocity ellipsoids in each field divided by populations, turnoff, RGB and blue MS.
