calibrate()

virtual MdtCalibOutput IMdtCalibrationTool::calibrate ( const EventContext & ctx, const MdtCalibInput & hit, bool resolFromRtrack = false ) const

pure virtual

Convert the raw MDT time (+charge) into a drift radius + error.

It returns whether the conversion was successful.

Parameters

[in,out]	hit	Hit must have pointer set to the MdtDigit, as well as the global hit position (including the position along the tube!)
[in]	signedTracklength	the track length from the 'triggerpoint' to the hit. It is used for the time-of-flight correction. This triggerpoint is the I.P. for ATLAS p-p collisions, typically scintillators in test-beam and cosmic teststands, and not clear yet what is it is for cosmics in ATLAS. The sign is for determining the sign of the time-of-flight correction. If a muon first passes the triggerpoint, and then the MDT tube, the sign should be positive (the case for ATLAS p-p and H8 test-beam). If a muon first passes the MDT tube, and then de triggerpoint, the sign should be negative (typically the case for cosmic-ray teststands).
[in]	triggerTime	the time of the 'triggerpoint' in ns. This is the time (measured with the same clock as the MDT TDC's) when the muon passed a known point in space: the 'triggerpoint'. For ATLAS this is 0.0 since the TDC's are synchonised w.r.t. the bunch-crossings. For H8 test-beam it is the trigger time, which is time when the muon passed the trigger scintillators. For cosmic-ray teststands it is usually also the time when the muon passed the trigger scintillators. For cosmics in ATLAS it is not clear yet.
[in]	resolFromRtrack	indicates the method to provide the resolution as a function of the distance of the reconstructed track from the anode wire instead of the drift radius

calibrateTwinTubes()

virtual MdtCalibTwinOutput IMdtCalibrationTool::calibrateTwinTubes ( const EventContext & ctx, MdtCalibInput && primHit, MdtCalibInput && twinHit ) const
