Notes and Further References
Previously, there were two other programs, demojob and
midad . These are now obsolete and should not be used. The
midad one is gone and demojob may disappear in the
future.
See the section on running with
libMidad for details on the event display.
Exercises
Make sure that you have carried out the
preparation
steps.
Run loon with a simple event dumping module:
loon -q run_EventDump.C $ROOT_DATA/fardet_data/2002_06/F00005963_0000.mdaq.root
The -q tells loon to quit when its done, rather than leave
you at the interactive prompt.
Look at
run_EventDump.C
to see if you can understand what its doing.
EventDump is a simple event dumper module.
