    "abstract": "Using a quadratic saddle-point approximation, we show how information about a\nparticle-emitting source can be extracted from gaussian fits to two-particle\ncorrelation data. Although the formalism is completely general, extraction of\nthe relevant parameters is much simpler for sources within an interesting class\nof azimuthally symmetric models. After discussing the standard fitting\nprocedure, we introduce a new gaussian fitting procedure which is an\nazimuthally symmetric generalization of the Yano-Koonin formalism for\nspherically symmetric sources. This new fitting procedure has the advantage\nthat in addition to being able to measure source parameters in a fixed frame or\nthe longitudinally co-moving system, it can also measure these parameters in\nthe local rest frame of the source.",
