    "abstract": "Through the simultaneous measurement of the transverse size as a function of\nlongitudinal position, and the longitudinal distribution of luminosity, we are\nable to measure the $\\beta_y^\\ast$ (vertical envelope function at the collision\npoint), vertical emittance, and bunch length of colliding beams at the Cornell\nElectron-positron Storage Ring (CESR). This measurement is possible due to the\nsignificant ``hourglass\u0027\u0027 effect at CESR and the excellent tracking resolution\nof the CLEO detector.",
