3 TOF DA for online calibration from pulser data
5 Contact: Chiara.Zampolli@bo.infn.it
6 Link: www.bo.infn.it/~zampolli
9 Number of events needed: 10000
10 Input Files: TOF<nrun>.raw, where <nrun> is the run number
11 Output Files: TOFoutPulserLDC_<LDCid>.root, where <LDCid> is the id of the LDC which is read (2 characters field, e.g. TOFoutPulserLDC_03.root),to be exported to the DAQ FXS
12 Trigger types used: PHYSICS_EVENT (for the time being)
