Distribution of the latitude for the poles of 18 Flora family asteroids. The zones referred to in the abscissa are defined with the same conventions as in Pravec et al. (2002), representing approximately equal surfaces on the λ,β sphere; region 1 means retrograde, from −90° to −45°, 2 means −45° to −25°, 3 means −25° to −8°, 4 means −8° to 8° (prograde) and so on. The histogram looks exactly the same if we put the spin vector north pole obliquity in the abscissa.
