X-Git-Url: http://git.uio.no/git/?a=commitdiff_plain;h=988dd3a4ffbc307e35f79eeacd6db35f7d32f8aa;p=u%2Fmrichter%2FAliRoot.git

Fixing the AliTriggerAnalysis in order to use the VZERO average times and the decisions stored already in ESD. The backward compatibility is fully preserved. For the moment the online trigger analysis is disabled (returning always b-b). It needs some work on the reconstruction side in order to add the b-b flags for simulated data into the ESD (for raw data they are already there).
