2 T0 DA for online calibration
4 Contact: Michal.Oledzki@cern.ch
5 Link: http://users.jyu.fi/~mioledzk/
8 Number of events needed: 500000
9 Input Files: inPhys.dat, external parameters
10 Output Files: daPhys.root, to be exported to the DAQ FXS
11 Trigger types used: PHYSICS_EVENT
12 ------------------------------Alla
13 Now trigger type changed to CALICRATION_EVENT
14 to have data during test.
15 SOULD BE CHANGED BACK BEFORE BEAM
16 ------------------------------- Alla
