20 // TTask derived class to perform the various calibrations.
22 // This task takes the current event in memory and uses the attached
23 // OM database to access the various calibration functions.
24 // A specific OM database may be attached by means of the SetOMdbase()
25 // or SetCalibFile() memberfunctions.
26 // Further details about the OM database can be found in the docs
29 // In the calibration procedure, all event data in memory is scanned and
30 // replaced by calibrated data if a calibration function is present.
31 // When data is succesfully calibrated, the corresponding de-calibration
32 // function is stored in the event data at the appropriate place to allow
33 // access to uncalibrated data as well (see AliSignal::GetSignal for
35 // When the input event in memory already contained calibrated data
36 // (i.e. de-calibration functions are present in the event data), the event
37 // data is first de-calibrated (using the corresponding de-calibration functions
38 // contained in the event data) before the new calibration is performed.
39 // In case no corresponding calibration function is present, the calibration
40 // of those specific data will not be performed.
41 // This implies that running this task on calibrated data without having
42 // attached an OM database, will result in fully de-calibrated data.
43 // In case an OM slot was flagged as bad in the OM database, this flag
44 // will be copied into the event data for the corresponding OM.
