Selected H1 Eventdisplays
Here you find events selected by Joachim Meyer.
The selection contains events which demonstrate PHYSICS or DETECTOR
PERFORMANCE in a convincing way.
There exists a folder with these event pictures
in J. Meyer's office (DESY Lab 1A, 329) which you are invited to inspect.
In that folder you also
find a colour-foil copy of the events for urgent use.
The 'Standard view' contains : BIG r-z view (no iron), small r-phi view (no iron), E- lego plot
