You may need to define the environmental variable STAR_REF:
setenv STAR_REF /afs/rhic/star/starlib/ref
On deneb, in ~staronl/ana, type trkStaf to bring up
Staf. You want to bring up a HIGZ window, so give a carriage
return to accept the window when you get the ``Workstation type'' query.
Then
exec init
to initialize.
The other defaults should work.
If you have trouble connecting to netfeed1, clear it: exit
Staf, then
close netfeed1.
To take data,
exec go N
where N=number of events to analyze. If N=1, a detailed picture of
the event is produced. If N>1, various (faster) plots are displayed
every 10 events. Use cntl-C to exit go.kumac at any time.
Next: Data Output Up: On-line Analysis Previous: Starting on-line analysis
Histograms are created by histos.kumac and filled by
go.kumac.
An output file of histograms is named with the date and time in its
title by default in init.kumac. The files are written into
~staronl/ana/histos. The file is updated every 50 events in
go.kumac, and also when go.kumac returns.
The present method creates one file for every Staf session;
to create a new file requires exiting and restarting Staf.

All read events are written in raw form to
/home/deneb/star7/sys_test for sector testing or
/home/deneb/star7/tpc_test for data taken on the TPC.
Files created in this way will, in general, contain a subset of
the events written to tape.
