  In this work we study the temperature dependence of the equilibrium variance
of critical fluctuations near the QCD critical point. In particular, we take
the finite size of the fireball created in heavy-ion collisions into account
and systematically obtain corrections to the leading-order result. We find that
not only is the variance globally reduced in a finite size system, but for
certain combinations of parameters a two-peak structure can develop for
temperatures near the critical point.
