In routine operation the Cornell Electron/positron Storage Ring, CESR, collides 9 trains of 4 or 5 bunches of electrons and positrons. The luminosity of individual bunch pairs can suffer if the transverse positions of those bunches are displaced differentially. This paper will present the results of studies of the effect of bunch-by-bunch or trainby-train variations in the luminosity by measuring (1) the deflection from the beam-beam interaction, (2) the relative positions of the bunches, and
more » ... ) the bunch dependent luminosity from the CLEO detector. Comparisons between these three methods are discussed.
