  Motivated by the finding that the observed surface brightness profile of many
galactic nuclei are well fit by double-power-laws, we explore a range of
spherical self-consistent dynamical models with this light profile.
  We find that the corresponding deprojected volume density profile, phase
space density and line-of-sight velocity distribution of these models are well
fit by simple analytic approximations. We illustrate the application of these
models by fitting a sample of about 25 galactic nuclei observed by Hubble Space
Telescope. We give the derived volume density, phase space density, velocity
dispersion and line profile parameters in tables. The models are useful for
predicting kinematic properties of these galaxies for comparison with future
observations. They can also be easily applied to seed N-body simulations of
galactic nuclei with realistic density profiles for studying the evolution of
these systems.
