noimg: \small Properties of colour reconnection models.: \small Tuned JETSET 7.4 parameters without and with inclusion of CR. Azimuthal isotropy in the parton shower is assumed (MSTJ(46)=0), since this option gives a better fit to the data. Any parameter given without error is fixed during the fit procedure. The fraction of reconnected events is given in the last line.: \small Tuned ARIADNE 4.08 parameters without and with inclusion of CR. Any parameter given without error is fixed during the fit procedure. The fraction of reconnected events is given in the last line.: \small Tuned HERWIG 6.1 parameters without and with inclusion of CR. Two cluster model parameters, CLSMR and PSPLT, have been made flavour-dependent in order to better describe the measured B-meson fragmentation function. The D-wave meson multiplets are switched off. Any parameter given without error is fixed during the fit procedure. The fraction of reconnected events is given in the last line.: \small $\chi^2$ values for the event-shape and charged particle momentum distributions used in the global fits. The total $\chi^2$ values for the fits using restricted regions are given in the last line.: \small Statistics generated for each QCD Monte Carlo model.: \small Some properties of energy-ordered jets in data.

\small The charge distribution of jet 3 (the lowest energy jet) compared to JETSET predictions without and with colour reconnection.

\small The distribution of the number of charged plus neutral particles in the rapidity interval $0 \leq y \leq 1.5$ for jet 3, compared to JETSET without and with CR.

\small The charge distribution of jet 3 for a rapidity gap in $0 \leq y \leq 1.5$.\small The relative model--data differences $\delta$ in the rate $r(0)$ of neutral jets for jet 3 as a function of the upper limit of the rapidity gap. The points at $y_u=0$ correspond to the full sample. Statistical uncertainties of the data and the Monte Carlo calculations are shown as error bars.Caption not extracted
