Figure 31: Shown on the left is the Z mass in the muon and electron channels used for setting<br />
the energy scale of the calorimeter. On the right are plots of the resolution of the calorimeter<br />
or tracking chamber, versus the r<strong>at</strong>io of the tted Z mass to the LEP measured Z mass.
