Abstract
The authors give a complete description of 'standard' N=2 Poincare supergravity in harmonic superspace. The main constraint they impose is preservation of the analytic subspace by supergravity transformations, so as to allow the coupling of supergravity to analytic matter superfields. Supplemented by 'conventional' and conformal breaking constraints, this requirement is shown to define the whole theory in terms of an unconstrained analytic prepotential.
