The gravitational wave signal arising from the collapsing iron core of a TypeII supernova progenitor star carries with it the imprint of the progenitor'smass, rotation rate, degree of differential rotation, and the bounce depth.Here, we show how to infer the gravitational radiation waveform of a corecollapse event from noisy observations in a network of two or more LIGO-likegravitational wave detectors and, from the recovered signal, constrain thesesource properties. Using these techniques, predictions from recent corecollapse modeling efforts, and the LIGO performance during its S4 science run,we also show that gravitational wave observations by LIGO might have beensufficient to provide reasonable estimates of the progenitor mass, angularmomentum and differential angular momentum, and depth of the core at bounce,for a rotating core collapse event at a distance of a few kpc.
