Detailed Description

Object storing per-hit information from a track fit.

Version

1.0

This object stores the information related to each hit from a track fit. In particular it stores the 1D hit position measurement (TrackFitHitInfo::fHitMeas) and its squared uncertainty (TrackFitHitInfo::fHitMeasErr2), the ids of the wire where the hit is found (TrackFitHitInfo::fCryostatId,TrackFitHitInfo::fTpcId,TrackFitHitInfo::fPlaneId,TrackFitHitInfo::fWireId), the track parameters (TrackFitHitInfo::fTrackStatePar) and correspoding covariance matrix (TrackFitHitInfo::fTrackStateCov). The track parameters need to be defined at the wire location, and, in order to make and unbiased comparison of the hit and track parameters, they should be obtained without using this hit in the fit.
