if you want to change the LVL2 Trigger settings do the following:
go to one of the lxi-machines (user hadaq):
$ ssh hades@lxi016
then go to /u/hades/hades-lynx/aug04/slow
hades@lxi016:/u/hades> cd hades-lynx/aug04/slow/
here open the file trigconc_p.tcl in an editor:
hades@lxi016:/u/hades/hades-lynx/aug04/slow> emacs trigconc_p.tcl
search the following passage:
set mu(lvl2_trigger_rate_reg) 0x04
# this register turns on and off the Matching Algorithm
set mu(always_negative_triggers) 0
here you can change the downscaling factor (currently 0x4) and turn on and
off the MU-algorithm.... (write a 1 to "always_negative_triggers").
That's it. Save file and at the next restart the new settings are loaded...
