StEvent - and now ?
The next step is to familiarize yourself with StEvent. You should get a copy of the latest StEvent documentation from:
http://www.star.bnl.gov/STAR/comp/root/special_docs.html
Get the manual in either PS or PDF format. If possible take the latter since it allows you to use hyperlinks.
There’s a User Guide and a Reference Section. Read the User Guide, check out the Reference if you are looking for someone specific.
Also very useful is the StarClassLibrary manual since it is used extensively in StEvent. See same URL as for StEvent.
