resolving new library dependency libAOD

[u/mrichter/AliRoot.git] / T0 / T0Physda.cxx

/*
T0 DA for online calibration
 
Contact: Michal.Oledzki@cern.ch
Link: http://users.jyu.fi/~mioledzk/
Run Type: PHYSICS
DA Type: MON
Number of events needed: 500000 
Input Files: inPhys.dat, external parameters
Output Files: daPhys.root, to be exported to the DAQ FXS
Trigger types used: PHYSICS_EVENT
------------------------------Alla
Now trigger type changed to CALICRATION_EVENT
to have data during test.
SOULD BE CHANGED BACK BEFORE BEAM
------------------------------- Alla
