Detailed Description

Composed recHit representing a pair of reconstructed hits

For each signal theLeftHit in the DT wire, two hits can be constructed, due to the Left/Right ambiguity, which can be solved only associating several hits together. This class describes the pair of points associated to a single TDC signal. The two hits can be accessed via recHits() method. The position is the average of the theLeftHit and theRightHit hits, namely the wire position.
