Abstract :
In a storage ring the existence of skew quadrupoles, solenoids, and other coupling elements breaks the independence of the horizontal and vertical motions. With the flat beams used in electron/positron colliding beam storage rings this coupling results in an increase in the vertical beam size with an attendant loss in luminosity. By defining a `badness´ parameter Bc the luminosity loss can be directly related to measurements of the coupling
