Extended Data Figure 4: Anisotropy and orbit type distribution as function of radius.
From: A supermassive black hole in an ultra-compact dwarf galaxy
a, β and βz shown as solid and dashed lines, respectively. Anisotropy 
indicates the relative size of the velocity ellipsoid in spherical coordinates and it is relatively constant over the radii probed by the kinematics. On the other hand 
(in cylindrical units) gradually declines. We note, however, that the velocity ellipsoid cannot be aligned with the cylindrical coordinates throughout a stellar system, and thus a physical interpretation of βz is not straightforward. b, The relative orbit fraction as function of radius.
