There are four areas of information and actions placed around the event display:

Event Selection

Event Information

DELPHI

The Event Selection contains a list of all the events. Any event can be selected. To choose the next event just click on >.

The Event Info contains for example the multiplicity of the charged particles and the detected (visible) total energy.

A short description of some of the detectors can be seen under Detectors on Hoc hub. The detectors in the barrel and the forward/backward regions are selected separately.

Rotation and zoom are handled by the mouse. The zoom enlarges the magnification by bringing the mouse from the centre outwards (pressing down the mouse button). The opposite direction decreases the magnification. The "end view" and "side view" shows the detector from different sides.
