  The topological order of a (2+1)D topological phase of matter is
characterized by its chiral central charge and a unitary modular tensor
category that describes the universal fusion and braiding properties of its
anyonic quasiparticles. I discuss the topologically invariant quantities
associated with these and identify ones that are useful for determining the
topological order. I propose a variety of physical experiments that probe these
quantities and detail the relation of the measured data to the topological
invariants.
