Query: Discrete series characters for affine Hecke algebras and their formal
  degrees   We introduce the generic central character of an irreducible discrete series
representation of an affine Hecke algebra. Using this invariant we give a new
classification of the irreducible discrete series characters for all abstract
affine Hecke algebras (except for the types E) with arbitrary positive
parameters and we prove an explicit product formula for their formal degrees
(in all cases).
