In heavy ion collisions resonances can create strong non-Gaussian effects in the two-pion correlation function. Hence, the commonly used Gaussian fit parameters do not fully characterize these correlators. We suggest a different set of HBT parameters which does not presuppose a particular shape of the correlator and allows one to extract additional information not contained in the Gaussian fit parameters. Within a simple model for an expanding source including resonance decays it is shown that this additional information provides a clean distinction between scenarios with and without transverse flow. {copyright} {ital 1997} {ital The American Physical Society}
