Figure 4:
The probability,
,
that the observed dwarf
sample stems from a parent isotropic radial power-law density
distribution with index p. The number of innermost dwarves in
the sample (Table 1) is indicated by the numbers.
Thus 11, for example, means that the innermost N=11 dwarves
(out to and including LeoI) are compared with the isotropic
power-law distribution. The thin curves (and numbers in
parentheses) are probabilities calculated by excluding SMC and
UMi from the data; here N=(9) incorporates all dwarves except
SMC and UMi out to and including LeoI (Table 1).
The increase of
with decreasing N and
(N) is a result of weakening confidence as the number of
observed data is reduced. The decrease of
for p>2.4 comes from the theoretical
distribution being increasingly concentrated towards the
Galactic centre while the plane lies off-centre (
