The results of fits of the two-particle double-ratio correlation function $R_{2} (Q)$ for $\sqrt{s} = 0.9\ TeV$ events with the unlike-charge reference sample for various multiplicity intervals $n_{ch}$ for the exponential parametrization $\Omega^{(E)}$. The uncertainties for parameters $\lambda$ and $R$ are square root from the quadratic sum of statistical and systematic errors. Where only one error is shown for parameters $C_{0}$ and $\epsilon$, this represents the statistical uncertainty only.
