Toward the energy and the system size dependece of elliptic flow:   working on flow fluctuations
  In this talk I concentrate on two topics closely related to the understanding of the energy and the system size dependence of the elliptic flow: determination of the elliptic flow ($v_2$) ``free'' from the effects of non-flow and flow fluctuations, and the role of fluctuations in the initial eccentricity of the overlap region. I introduce a new approach for the analysis of the distribution in flow vector, $dP/dq_n$, namely, I propose to use the Bessel Transform of this ditribution. I show that the Bessel Transform method is similar to the Lee-Yang Zeroes method, and is very transparent in its meaning and applications.
