Well this is completely diffrent - I am taliking about trigger levels - for
once not software reduction.

Level 0 (t0)
Level 1 (detector specfic triggers (in coin with t0))
Level 2 (triggers that requires fast clear/aborts)
Level 3. Software in either front end processors or right after event
collection, that trhows events out and/or modifies. At some level the TPC
front end has level 3 code in as the data are reformatted (reclustered). But
one
could in fact easily (well ?!) implement code that could do e.g.
reclustering, reduction if not valid hits etc..
