43// TOF preprocessor class.
44// It takes data from DCS and passes them to the class AliTOFDataDCS, which
45// processes them. The result is then written to the CDB.
46// analogously, it takes data form DAQ (both at Run level and inclusive -
47// of all the runs - level, processes them, and stores both Reference Data
48// and Online Calibration files in the CDB.
